Repairs for almost 2 months

I purchased a Blackview Tab for my son last year June. And within 6 months the tabs battery started giving problems. It's my fault for taking the tab in for repairs after the 6 months. I purchased this tab at the Promenade branch. Sales Assistant was Megan who was very nice and helpful. Now upon taking the tab in for repairs, mind you, this tab never fell and does not have any cracks on the screen nothing. It's just the battery. It's been 2 months and I have heard nothing from them. Went to the store twice only for Megan to tell me that she will call me but she never does. I saw the report and on the report it's written "damaged screen", I'm sorry? If I take that tab and the screen is cracked, there will be hell to pay. I handed that tab in with no cracks on the screen. Repairs is supposed to take up to 21 days but it's been 2 months and they wanna quote me R1500?

I am never purchasing anything from this store again. Very unprofessional
