Bad service

I took my phone in for repairs under warranty in Newcastle Mall Ackermans in Kwazulu-Natal on the following date 04 January 2018, today marks full seven weeks still without my phone, i have been calling them for weeks but yet not even one of them in the store got me helped including their Head Office. I want people to know what sort of bad service will they get when they are buying from Ackermans, i even asked for my money back to go buy a cellphone from elsewhere because i have to use my phone for work but now how am i going to complete my daily tasks when i have to ask my colleagues to swap sims if i have to make calls? Ackermans has shown me how bad their service is and i will never ever buy anything from them if this is how they run their business.
