Samsung India — Very poor service offered by mangalmurti enterprises, thane service center

Address:

Thane, Maharashtra, 400608

I submitted my tab 3 for check up on 5 nov. No call received from service center regarding estimate to repair device. After 10 days of follow-up and multiple reminders to call back, they didn't respond. I had called the landline of the service center and it is never available. You may check[protected].
Today when i called the customer care and took the number of the store manager, and finally was able to speak with them.

After 10 days of follow-up, they are now saying that the montherboard is damaged and repair cost rs.9058/-. No one called to give an estimate of repair and take confirmation of repair.

In my two calls to the customer care, they had suggested only damaged sim slot is ordered (Again without my confirmation) and delivered to the center.

Nazneen from the service center talks very arrogantly to the customers.

I had been a loyal samsung user, but this experience makes
