Poor service

I have recently noticed that my monthly amount that I am billed for on my Vodacom contact has increased by around R200 and I cannot understand why. When I look at the Vodacom app which allow you to monitor your data and calls it is already displaying a amount of almost R800 (should be R549)which makes no sense as I have not used all my data or free minutes??? I have emailed the accounts department and provided my ID as well as a letter requesting itemised billing for the last 4 months and have had no reply. to add to that I received a call from the customer care department yesterday to enquire if I am happy with my contract and when I informed Bianca of the situation she assured me that she would fast track my request by logging a call to the relevent department and they would call me within the half hour, whereby I can give them the reference number that she will send via sms to me right away....-needless to say its almost 24 hours later and I am still waiting for the sms and have received no further assistance which makes me wonder if the call was ever logged in the first place??<br> <br> thoroughly disappointed in the level of service that Vodacom delivers<br>
