Mi — services rendered by service centres

I purchased MI note 4 as on a particular date. After some months while using phone suddenly phone itself switched off. I went to service centre for the same. They took the phone and checked. They informed us that the phone has suffered from liquid damage but originally it was not. The phone was IN warrenty and they were charging Rs.3609 for the same. We complained for the same in Consumer Forum as they were charging costs unconditonally. As the company is good for the phone manufacturing but the service centres are BOON in the name of company. They take so much time in checking the phone and WASTING the time of consumers. I mean seriously the company should work on the services rendered by you. We are totally DISSATISFIED with the services of the company. After all this, I seriously recommand NOT TO BUY MI PHONES.
