Telkom wi-fi cancelation of contract

Good evening ,I have a Wi-Fi contract(fibre) with telkom,my contract was for 2 years.I paid for the full 2 years,now its a month to month.I have been trying to cancel my contract for the past 2/3 months now account is paid up to date..the problem that I experience is that nobody can assist me to cancel the contract,I was in store at Parow centre a few times they claim that it needs to be done online or on the phone with one of their agents.When you call the numbers they give ,they either give you another number to call or they transfer and cut the call.I recently went again to the Parow centre branch they logged a case for it to be dealt with but the consultant informed me now that the case is still open and I must wait.The more longer they take to cancel..the more I end up paying.I don't think this is fair because when we take out a contract everyone is standing ready to assist but when you want to cancel their is not even one person that can help,they are basically robbing the poor man that doesn't have fancy lawyers.
