Still no credit on our account that was billed incorrectly

<p>we are very loyal Vodacom customers with more that 5 contracts registered on my Husbands name. 2 months ago our account was billed incorrectly but we still had to pay R 1000.00 extra for the incorrect bill as our contracts wouldve been locked. this was out of our budget but we paid. now - 3 months later the credit has still not been given. when going in to vodacom there is a waiting time of 2 hours + and when someone does eventually help you then they have to phone head office just to be told that the account will be credited but when the next payment date comes - THERE IS NO CREDIT. We do not have the time to drive back and forth to plead for our money that we paid vodacom in advance just to not let the credit be credited on our account. we have all the proof and will take legal action if Vodacom does not sort this out immediately! our contracts are discontinued if we do not pay on the specified date - but your loyal customers that pay your salaries has to wait 3 + months to get their credit! WHAT CUSTOMER SERVICE IS THIS!</p>
