Useless Service

<p>I have had a data contract with Telkom Mobile which the contract was ending at the end of April, I was advised that I needed to fill out a cancellation form in March so that my last debit order would go off at the end of April. They still have not cancelled my contract after calling several times and we are now approaching the end of May</p> <p>Can somebody please explain to me why they are refusing to cancel my contract because what they are doing is ******* after me submitting a cancellation request.</p>
