Telkoms ineffeciency

Hello Peter. I have been having problems with my speeds from Telkom. I have called the call center on a number of occasions but my problem has not been resolved as yet. I had a 4 meg line and recently upgraded to an 8 meg line and I am receiving speeds of a 1 meg line. I spoke to an excellent consultant today whose name is Maria and was informed that there is a problem with the underground cable which is affecting my speeds. Maria Oliphant was the very first consultant to do a test where she had to cut off the call and call me back after the test. On a previous occasion I had a consultant come out to do a test. He informed me that there was a problem with the underground cable but he would switch the ports and see if it works.This shows that Telkom knows that there is a problem but is doing nothing about it. I am paying for a service that I am not receiving. Is it not theft when money is taken and the service is not provided . Please can you help me with this issue. Regards Pranil
