Missing airtime and data

On the 16/03/2016 I had an airtime balance of R544 and a data balance of around 1gb. I did not use the phone all day and even had the data turned off on the phone. When I checked my balances the evening it was all zero.<br> <br> I called the Vodacom customer care number on 111 and lodged a complaint/query. I was told it would take 7 to 14 days to resolve and get back to me. It's been 22 days now and after several calls to customer care and even speaking to their solutions department no one is able to assist or tell me what went wrong. All they can tell me is that the system shows the query is still in progress.<br> <br> I find this completely unacceptable as I have paid for both the airtime and data and now am unable to use it as it has just disappeared from my account. This is the second time this year that I have had problems with this contract since taking it out in December 2015. Vodacom's customer service and service in general is really going down. I have been a contract customer for more that 10 years with no problems, but lately their service is not up to par.<br> <br>
