Old Service not available at new address

I relocated my services on the 03/08/2015. When the technician installed the ADSL line, the speed which I had at my old address was not available (40mb). The line at the new address only syncs at 6mb and Telkom do not offer a 6mb service. I tried calling on that day and held on for 45 minutes twice with no response. I tried the chat service online and had the same result, no agent connected in 45 minutes. I then posted on twitter and have been told they are taking care of it. it has be 10 days and still it hasnt been sorted. They say an agent is attending to it and keep asking me the same question. I would like this to be sorted out as soon as possible. I am paying for a service which I am not receiving. This request also needs to be back dated to the installation date. I am highly annoyed at having t follow up with the ridiculous response times.
