Minimal Internet Speeds

Still no response from Telkom. I ordered a 4MB line, however I am only a maximum of between 0.8MB to 1.2MB line speeds. I logged a fault to resolve this(1264CRK140415) and the log was closed saying the issue has been resolved. No technician was sent out. I then escalated the fault and still waiting for someone to contact me. We don't have a choice as to who provides our fixed lines in South Africa so we are forced to use this Telkom as a \service"provider. Can someone please sort this out. Don't know who is worse at the moment"
