Pathetic Telkom Customer Service

We have taken telkom as our internet service provider in our holiday home in the Strand. Our cap all over of a sudden just disappeared. We bought 100 Gig extra and although it showed that there was more than 90Gig left the morning after it disappeared again within an hour without any usage by ourselves. We tried to speak to the customer services dept on numerous occasions but were cut off every time before we could get an answer as to the problem. The same happened on the Live Chat platform. We then send an email but to date received no response and have no internet connection anymore.
