Telkom frustrates the consumer

Last year I paid Telkom for a landline and the money went missing. After many conversations and six months later the money was found in another Telkom account. However I cancelled my service with Telkom a month after the money went missing but Telkom kept on billing me. More conversations, more e-mails and a promise that all "debts" incurred will be written off up to date of cancellation. Eventually some small amount was written off but not up to date of cancellation - and I queried once again . Now the debt collectors want to summons me. It seems as if Telkom would rather frustrate the consumer than sort out their mess.
