Bad Service

Good Day,I am really disappointed by Blue Label Connect,i currently have a contract with them,and i was one month behind with my payment,and i made arrangement to pay until i am up to date,unfortunately they closed my contract sim card without them informing me,Right now i am unable to make calls,i have been calling for the last 3 month for someone to help me open it since they are taking money from my account every month but i don't have airtime,no one has ever come back to me everytime i call i have been told that they have escalated the matter to someone will call me back,yesterday i called and spoke to Tino,he told me the same thing this morning i called again spoke to Happy he was rude, constantly interrupting me and telling that i have to buy a new sim cared to do a swim swap, i asked him why do i have to by a new sim card since they are the one's who had closed my sim card? The call got cut off and no one I mean no one has ever came back to me, i am honestly depressed with Blue Label, I am unhappy with their service, and I would never advice anyone to take a contract with them at all.I had told them that i would like to cancel my contract with them no one is seems to take heed to my request that are telling me that i have to pay them,for what i dont know exactly,i am so emitionally drained to call them,getting to talk to their staff who do not have an ounce of customer care at all.i just want to cancel this contract if they have,and they should stop taking my money from the bank evey month,i am sick and tired of them.I am having constant headaches with this issue,been send from pillar to post.
