Webafrica Is the worst company

I took out a sim only deal with Webafrica and the delivered a faulty sim card, and charged me for redelivery of a sim card, over and above that they billed me for a month i never used since they activated a faulty sim card still charged me after i told them i have never used their services and that they shud check the usage meter for confirmation. The bill has increased to R600 for a product i have never used worse the second sim card was sent 2 weeks ago and it still has not arrived. I contacted Webafrica and Thandazani one of the consultants along with his manager promised to rectify my issue and to reverse the funds, but rather i keep seeing the amount increase while im not even using the services since i have no working simcard. the business has been transferring me from 8am until 8pm sending me from pillar to post without any assistance they jst blind transfer you to the next department without helping. its been 2 weeks since this is going on and 2 months since i took the package. I have lost all hope in getting assistance since no one wants to help me within the company, i have cancelled the service with immediate effect but i still get billed and I really don't know wht to do now since WEBAFRCA doesn't want to help its customers. i wish i cud make a huge billboards to to show their garbage service. Today i have been transferred since early this morning even now i have screen shot of how you wait and when you've explained they transfer you. and the next agent does the same
