Customer exploitation and abuse

<p>In 2013 my wife and I took a 2 years cellphone contract with Telkom Mobile from Montana branch in Pretoria. Telkom mobile number ********** 205. We approached Telkom for a cancellation of the contract in 2014 but were told to wait for the full contract duration to deplete, which we did. Telkom to date still deducts money from our bank account even though we have visited numerous branches to cancel the contract which is actually expired. We are now in the second year post contract expiration and we are not using the service but Telkom continues to deduct money from the account. This is *******, abusive of Telkom and exploitation of consumers. None of our queries are responded to. Can Telkom just cancel the contract and repay our money. What are our rights to sue them?</p>
