ADSL Speed

Ive been struggling for the past 5 weeks with the same problem. This is the 2nd time im reporting Telkom. Ive phoned them 3 times and 3 times they promised that someone would come to assess what the problem is. They never showed up. After i reported them they eventually sent someone to find the fault. The person told me that my router is faulty and that i should return it and ask for a new 1 since i only had the modem for 1 month when it started giving problems. I spoke with Craig at Telkom Vaal Mall and he refused to replace the router. He even asked his supervisor who also refused. I phoned them again on 22/9/17 and they again promised to send someone during the course of the weekend. They never showed up. Now im recieving messages saying that i must pay my account or my service will be suspended. Im fed up with this poor service. They are useless. I will never recommend anyone use Telkom.
