TRIPLE DEDUCTION AND BIG PROBLEM TO REFUND

Hi I am turning to Hellopeter due to the fact that I have already spoken to more then 3 people at the Call Centre and I have received no joy only excuses and delays. On the 12 November 2015 my bank account was debited 3 times for one access amount of R200. Oneplan deducted R600 instead of R200. I have called the call centre and spoke to Zarina Hartley initially, thereafter I made follow up calls to Trish, Makosazane and Sulezi to enquire of the status of my claim. Oneplan is quick to deduct your money owed to them, however when they owe you money the excuses they give is that they had a system error and that they are rectifying it for the past 2 weeks. The refund takes between 7 -14 days which is has now passed. I have been with Oneplan for a number of years and previously the customer service was of high standards, I am quiet disappointed at the recent customer service and I think that it is pathetic that nobody can give me an answer as to when I will receive my refund.
