Don't buy from Ackermans cellular

I bought a tablet from Ackermans, there was an issue with the sound so I took it in on the 9th of December 2019. I'm still waiting to find out what's happening. I've been into the store and they couldn't give me feedback, I've queried it with your online customer service consultants but they are waiting for feedback from the cellular department. This is really getting ridiculous, if I missed an installment, you would be in contact with me very quickly but when your products are faulty, I'm expected to sit and be patient and hope that something is being done about it, we're going on two months of waiting and I'm constantly trying to get answers.
