Dissatisfaction with Cell C ( Especially iLanga mall in Mbombela)

I opened a contract with Cell C Ilanga mall in Nelspruit where nothing was explained to me about the LTE-A just because they want to push their sales , a month and a half in the contract I went back to let them know that my device is not working , the said they are suspecting that they need to do a sim swap , my device still didn’t work , I went back to them and said the device was not working still , instead now they said I need to book the device in for repairs , I did that left the device with them , that was in January , I went there 4 weeks later to find out when will I be getting my device back only to find out that my device was never attended to , the moment I left the door they just left my device lying around unattended , they booked the device in for repairs in February , I went back again and they said they have ordered my device which will arrive within 3 days , I went back to them a day after the promised date , they still didn’t have the device , they only started acting on it when I got there , we had a big fight and they promised to get it resolved by first week of March 2019, I went there on the weekend and spoke to the area manager which still my device wasn’t ordered by them , I then had to succum to another date , I went there again today (21 March 2019) and still they don’t have my device , I am paying for this service monthly and for 4 months since my first visit I’m not taken serious I told them to cancel the contract and they telling me about a commitment fee but I continue to pay for something I’m not using is really painful , if I today decide to stop paying , Cell C will quickly place my name on ITC but when it’s them not rendering a service then it’s a different issue they can get away with it , I’m not happy please help me get out of this contract and terminate my relationship with Cell C

This is emotionally strainious
