Engineering-Sales, Products & Quality

I have been concerned with Quality Issues, not because I treat myself an expert of that discipline, but I consider that Quality is a Must, because seller charges for quality also, within price
It is a fundamental right of a customer to be provided with required quality
Manufacturer or industrialist do not do any obligation on their part in favour of customer. Simple equation is that Customer pays & manufacturer sells
Why should then bad quality products be accepted or be manufactured
This is a top burning question & also, this relates to all field of engineering
I have very bad experience of purchases simple products from internationally reputed organisers.
Recent examples, when I bought online on Microtech UPS for my computer, I paid demanded sale price & got delivery
Having installed it, it failed in just 7 days of installation
I complained & one part was replaced, blaming on voltage fluctuations
Till, order is delivered, many SMS are received, which is a good informative issue, but my requirement is not SMS, but Quality product
That UPS again broke during warranty period of 2 years.
I placed an order of 2 # HP wired mouses online & got delivery
When started using, one mouse did not work at all.
I sent a mail to agent of HP, but no reliable response, which made ma angry & to write scolding language to them
Then, after being helpless, I wrote to HP & they could not understand.
Then one mail was received that you have to write to someone else.
I got a call after that directed writing & disputed with them, because they again asked my what problem was
Means there exists no one in that section, even to read mails clearly
Again, I with high pitch language, explained to them & they asked me to contact agent, which raised my temperature & I shouted on them that it is your responsibility & solve it
After, received a mail, through, which they tried to teach me to talk politely & again I responded that you deserve such treatment
I wrote back & forced them that you have to do it
They asked me to go to their service centre, which further irritated me
Then I did it, but my visit failed to get me any result
Then I wrote to them a bombarding mail & asked them to get their Quality Certification copy
Really, I was too upset with functioning of quality system on products sales
I told then that you are not functioning, per quality certification, because you failed to check functioning of product, prior to packing
I told them that I shall impact your certificate & I was serious
Later, I got a mail that management is thinking to replace it & it would take 2 weeks
Then they tried to refer to another wireless mouse & not wired mouse
I replied to them that I required wired mouse
No solution reached till now
I am informing this to your guys, because I do not find any degree of seriousness of quality anywhere, whether it be construction of manufacturing or industry
Current generation is mobile born, air conditioned born, & they do not know impact of Sun & Thunderstorm
If there is no meaning of checking products, before delivery, where does quality exist?
It exists only in papers & customer is least bothered about papers
Quality Product is demanded & not SMS or packing
Swift service is demanded to replace bad products
It is not fault of customer, but seller or manufacturer
There are so many other instances that we face every day & you too may be facing, but seriousness nowhere exists
Construction in Civil engineering is number 1 dominating world, where no quality exists & people just talk a lot & do very little
Engineering Institutions failed everywhere to organise quality on products
Engineers have failed drastically, as far as, quality organisation is concerned
Whole team depends only on engineers!
It is only engineers that an change scenario or else!!!!!
