Cell C Pathetic customer service

Cell C is has the worst possible in store service, no one knows proper procedures to follow. I have been using Cell C LTE in my area from November 2018 till April 2019 with no issues. In early May I had complained that I stopped getting LTE service in my area and then logged a fault. I received a phone call from cell c customer care to cancel my contract as my area does not have fixed LTE anymore because previously they were using MTN towers and now they do not have the rights. So I went to the cell c store explained what has happened and all they did was log a fault which I already did which took over an hour. I went back a week later and told them that I am not getting reception and I am paying for no reason, I had handed over my modem and sim card. After it took them 2 hours to load an image of my modem onto their system, the manager said that now it is in the process of being cancelled and that I need to wait for a further reference number. Its been 2 weeks already , my account has been debited again and i am still waiting for this "last" reference number. This is now the 2nd month that I am paying for no reason. I am extremely disappointed. I urge others to not support Cell C, especially the Galleria and Bluff store unless you want to buy airtime because that's possibly the only service the employees can provide.
