What happened to customer service?

Hi, I sent an email to vodacom on the 8th August . No one even bothered to call me your voice automated system keeps telling me my account i in arrears.

The reason reversed the debit order is because your people at Vodacom charged me for a device that was faulty the device. The prorata was billed and a month in advance . Im still waiting for my account to be credited and a reversal to be done . Until the account is fixed which your people failed to do I will keep reversing the debit orders. Im disgusted in the service I received from Vodacom. you had the decency to call me to take out a new device ,now call me to fix my account. Infact i'm so disgusted i want to cancel my contact with vodacom. Vodacom has no sence of customer satisfaction none whatsover
