Worst Customer Service @Telkom Mall of Africa

I have had a contract with Telkom for the past 24 months, where I was contracted for a Huawei router. For the first 8 months of getting the router, I was not receiving any internet coverage. I then reported the matter. I was not assisted at all, it got to a point where I had to lorge a case to be refunded for the first 8 months, where I was paying for the router and not being able to use the internet. This case has been ongoing for 2 years now, no one seems to be willing to help. I've called customer service and followed their tedious and endless processes to no prevail. The store manager at Mall of Africa is the most *********** to say the least. I have back and forth emails with her regarding this matter and she always says "I'll escalate the matter". The floor manager of the same store!!! Why is he even the manager, he literally hides when I enter the store, that's how well they now know me. When I ask to speak to him, the consultants would say let me go check if is still in, 10 minutes later... "Sorry Mam he has already left," when I literally saw him when I entered the store. Telkom Mall of Africa branch has the worst service EVER!!!!
