Telkom 8ta Contract

I paid MTN a lot of money to move to Telkom 8ta 4 years ago, only to discover that I am in fact now with MTN-Telkom as my Service Provider.<br> My contract expired at the end of October 2015, and as yet I have not renewed or cancelled my contract, only to discover that it is costing me R200 per month more than I previously paid (no contract no handset) and yet I have to pay R521.50 per month, which I was told by Mr Elton Mofolo (Supervisor) is for the monthly Data . So before any calls are made, no new handset I have to pay R521.50??. I have during all the time with Telkom Mobile had to use a pre-paid number to phone my contacts from, as I could not receive or make calls due to bad coverage, all my calls went to voicemail, so I telephoned my missed calls from my pre-paid phone.<br> I would love for Telkom to explain what I am paying for.
