Misleading information

I've upgraded last year and I phoned vodacom's customer service 2 days after I received my phone to ask if I will be charged extra for data usage and this lady told me no I will not be charged because I am on a BIS package . 2 weeks after that my account has been suspended because I know own vodacom a huge amount of almost R22 000 . I've phoned Vodacom on the 29 of December 2014 and I've spoken to several people and no one has come back to me yet . I've spoken to Justice, Amanda, Pumeza, Buzi , Tuliwe and ****obiele . They've all told me that this should've been shorted out along time ago and they will escalate it to their managers and still no feed back . I've had it up to here and how long does it take to go and trace a call and just listen to it. I was told that a Pulanie Trok was working on this matter and that she's going to give me a call on the 29th of Jan or the next day and its the 3rd of Feb today. . I have 5 contracts at vodacom and they can't even sort out this one enquire and they do get their money on time each month for the past 2 years . its way to much and its starting to work on my nerves.*** are the number in questioning .
