Poor servuce

I cannot believe the poor, unacceptable, service that I am currently receiving from Telkom. I was informed that was due an upgrade, which I in fact was not, and after clearly stating on numerous occasions, that I cannot afford to pay more than what I am currently paying on my cellphone, the consultant added a second cellphone on to the existing contract and I am not paying over R400 more each month. I am irrate, and after numerous requests for help, I have been told that there is not much that can be done for me.
