Has not kept to promises

From January 2016 I've had hassles with my billing. I've called in on numerous times and as promised this would be fixed. Spoke to Chanello Delo, Ntando Nkosi, Mduduzi Ndlovu, Lungile Ngcobo of which all promised that my billing would be sorted and my spend limit would be at R0.00. To date this has not been done. I also inquired as to when my account would be credited with the R199 they debited me in November 2015. This has not been done. I have requested my call recording for when I've taken up the contract and still waiting. This is my last attempt as they are not responding to my emails. I will be in contact with the Ombudsman if no call is received within this week.
