Pathetic Service and no resolution

<p>I have been a Vodacom Customer for many many years and have now been appalled by the Service received. For 5 months i have not had a problem with my Wi-fi device that was capped at R178 per month for 2Gig of data. Now all of a sudden i get an account of R12885.31 for data used in 1 month???????? This contract was taken out and the consultant confirmed more than 3 times that it is capped and when the 2Gig of data is used it can't go over which the 5 month's so far have confirmed. After logging a call i got a reference number and i phoned back today to try and establish if it is the sim card number i gave the lady and the numbers corresponded. She then advised me after holding on for 30 minutes for a consultant that i had to now send it a letter to ask for a copy of my contract. I want this matter resolved as this is blatant ***** and i will take this matter further if this is not resolved.</p>
