Supa bad service

I called to cellc 7 times on the 17/05/2019. I spoke to many different agents who all of them were not even willing to assist. I spoke to Tebogo in upgrades after being transfered by their sales team so they can transfer me to cancelations and he hanged up the line. I called again spoke to mbali in customer care who I asked to speak to the Manager. I had to wait a while for the team leader by the name of mthokozisi ngobese to attend the call. I spoke to him. Told him that I Wana cancel an additional line that I was offered by them on Monday. I accepted cause of giving them benefit of a doubt that they do care about their customers after I had got a bad service when I called them on 16 May. I was transfered to cancelation and spoke to Shawn sakoor who told me he won't be able to assist me. He must put me through to another department. I have 2 contrscts with cellc now and I regret taking them they have the worst service. They forcing me to stay with the contract and they don't want to cancel the 3rd line cause they failed to diliver it for the whole week. My number is ********** 040
