The worst service ever!

I made a payment on the 1st of January and forgot to add reference number... Called the call center immediately and they gave me a proof of payment email address, 2 days later I get a response from *****do saying she can't allocate funds(no explanation), I call back speak to Nombuyiselo, Tebogo, Yurika, Matilda, Victoria, Portia in 3 days, who all say they are escalating and I must email to them(which I did) . I called again, the lady says 'all is well your services won't be disconnected, you don't have to call us everyday'... 10 days later my services are disconnected and Eklaar Shaik says he's escalating. I'm paying more for the calls than the actual service.. This is really frustrating.. TERRIBLE SERVICE.
