Lenovo — Smartphones - misconduct of authorised service center

I have a lenovo vibe x3, which had an issue with the charging. As the phone battery drained, the phone did not start again.

Since the phone was under warranty, i visited an authorized service center of yours (Technotronics technologies, ghatkopar, mumbai) to get my phone checked. I clearly explained that the phone is not starting and seems an issue with the charging.

The phone was checked by your engineers (Not in front of me), and the diagnosis given by service center was that the motherboard is faulty and needs a replacement. The estimate given was 8000.

Since it was too high, i decided not to get it done.

However, i suspected that the diagnosis might not be correct and wanted to take a second opinion. So i went to a local mobile service center who opened the mobile in front of me.

Firstly, the charging plate was tampered with, and the vibrator was missing from the phone. (Please note, that this was opened first time after i got the phone back from your service center).

Secondly, a simple diagnosis showed that the issue is not with the motherboard but with the charging plate only, as the battery once charged by alternate means made the phone switch on and work absolutely fine. I have got the charging plate replaced in less than rs. 1000.

What do i make out of this experience?

Is it a mandate from the company to service centers to make money by falsely changing parts? Or is it that the service centers are doing this at their own behest?

Please note, that by such incidents you are only increasing the statistics of failures in your phones, and also pissing off loyal customers.

I want to file a formal complaint against the service center, please tell me how to do so.

If you need any more details, kindly let me know.
