no internet service

3 weeks no internet. We contacted someone who knew someone. Got internet fixed. On for 2 weeks. Internet off again or so slow took 2 hours to upload 300k files. Worse service i can imagine. Cannot even get to call centre answer. Spent 14 hours accumlated, still no answer. Tel no ***. If not fixed soon we are going to another solution as our business is internet dependent. Spent over R3000 on data using cellphone to get files to clients, just because telkom service is non existent. They are costing me money and clients.
