Repairs on the Mobicell Fever Plus Tablet

I bought a Mobicel Fever Plus in December and early February it got stained without it having fallen down. We took it to Pep and was told it would take 21 days. It took 3 weeks for them to send me details as the amount to pay, without acknowledging whether it was a factory fault. We were told once its paid it will be a week but they have stock taking but since my son uses it for lectures they will try to hurry it up. I emailed proof of payment of 25 February 2020 and was told after a week due to stock taking. Today I called and was told their auditors came late to do stock taking and they will finish by the end of the week and then they will start with repairs next week. I asked the lady, what do we do currently. She kept telling about stock taking. They have such bad customer service. All I need is for the repair done and I will never recommend their products to anyone. No one has come back to ensure that I receive customer care. They do not care.
