They don't pay creditors

Worst service ever. Original agreement was fixed installment 54 months, the next thing they say It s 70 months. January I get an email that some creditors I will have to pay myself but the original agreement was they were gonna pay all of them. They started deducting in October and it turns out they only started to pay in January even them they pay an amount waaay less than agreed with the creditors. I get a call from Wesbank sending me to lawyers because since agreement debt busters has only paid 3 installment. R1600, R200, R1500 when the agreed amount for Wesbank was R3100. I always call they respond to emails after weeks, I get dropped on the call, airtime finishes I call again no solution.And they say they are not allowedto call the customer back. Now I have to deal with Wesbank having been paying debt busters since October. What a bad service.
