Bad service from Telkom

I have a LTE contract with Telkom, but have had endless problems! It is now about 8 weeks since I could last send an email, and for the last 5 weeks I cant receive emails either. After endless phone calls and contacts with the help of Telecom I was told that my email account is locked out! Yesterday I spent an hour in a Telkom shop and once again I received the same thing, a password to reinstate my email that does not work! I want to cancel my contract so I can get a new email address, but I still have about 14 months to go before my contract end!
