Worst service and lies from Cell C - Mimosa Mall

The worst ever service i have gotten from Cell C. I did my upgrade at the Mimosa Mall Branch in Bloemfontein. First they promised me data, which could then not be used on my number, so after a huge fight, we could get it cancelled and sorted out. Then 2 or 3 weeks after my upgrade, my phone crashed. I took the phone to Cell C MImosa and they said they need to sent it in for repairs. i followed up on Thursday 4 July, and then i was informed that no one knows where my phone is. Finally got hold of someone telling me they found the phone and someone will phone me back that day still. on Monday 8 July i followed up again, and then i was informed that a manager at the Mimosa Branch will phone me, because they should have phoned me already, as they need to give me a new phone. After that i am informed of a different story. no one gets back to me and if i follow up, every person i speak to tells me something else and the people at the Mimosa Branch keeps telling me that the manager is not available. the manager there is never available for a week now. I requested that i want to end my services with Cell C (as it is not even a month from the time that i upgraded). I need a manager or someone to get back to me. I want to end my services with Cell C or get a lawyer if this is not sorted out, because i am paying for something i am not getting. and i am being **** to by the staff of mimosa mall
