Worst service ever

This has been going on since March 2018. After waiting the 2 weeks they said it would take... nothing happened and I called again on Friday 12 July and logged another complaint ***1. Again I was told that all the information is right there!!!! Again I was told it was escalated to management. And once again, nobody did their job!!! On Thursday 25 July I called again and was asked to hold on for management after I insisted. You were manager on duty, Maguba M, but too busy to talk and I was told it was escalated and that you would call back... again an empty promise as I am still waiting. In the meantime, Nudebt call me 8-10 times every singel day from Monday to Saturday. They email and sms me all the time.. And refuse to stop unless you sort it out. It is enough to drive anyone insane!!!! It blows my mind that in the entire Telkom there is not one capable person who can credit my account back from December 2018 to April 2018, and to refund us the additional months my husband had paid???
