Failure to adhere to the agreed payment date

On the 28Aug 2015 multichoice promised that i should be refunded within 14working days due to them debiting the incorrect amount. It has been 15working days i have received no feedback, i feel that it is unfair that i would have to call them to follow up on the query that was not my fault to begin with. I was incorrectly debited becuase they claimed that i upgraded my package.<br> <br> Please get someone competent to get back to me ASAP, as it is very frustrating dealing with Multichoice becuase they keep shifting the blame!!! <br> <br> <br>
