Vodacom is the worst ever company!!

In 2007/01 I signed a 24 month contract with Vodacom which ended 2009. I send them a letter cancelling my subscription since there HSDPA My Gig 2.5 was the worst. Between 19h00 - 23h00 you could not stay connected for more than 15min before getting disconnected. I logged numerous calls and got told by techinician that they over sold the line and that is why it keeps on disconnecting, but would not admit it if we take it further. I just decided not to renew the contract and should have been the end of it.<br> <br> Now, 2015 I am told that I must pay \balance of contract"which i did not enter into. I told them more than 10 times to please email/fax me the contract I signed according to them"
