Bad Service

Yesterday morning I saw my internet was off. 8h00 I call 10210. I heard when they suspended my account. I then asked why. They see that my account has only a limit of R1500. Why I'm over my limit they can't explain to me because I'm not behind and my next due date is only for the 31st of March 2020. They then changed my limit to R3000. They tell me to access Telkom's app and follow my ref no ***. After 24hrs it is still on step 1. How hard can it be just to turn my internet back on. I work from home and now Telkom is holding me back from sending urgent work
