EXTREMELY BAD SERVICE

On 5th Nov 2015 took out a new data contract .BIG MISTAKE. Have had endless trouble since with my data.On 21 Jan I allegedly used my 5 gigs of data in 3 days. Find this extremely hard to believe as I was working 12 hour shifts. Mtn shop phoned and was told they will reset it as could be locked away ref *** Shahaan. Still no data. phoned again and told it would be reset.<br> 2nd Feb Mtn Glenfair ref *** Cheree ; put in a query follow up. Still no joy.<br> 4th Feb Mtn 808 ref *** Bongi; confirmed that package is only a night express. There is no such contract.<br> 9th Feb Mtn store ref *** Charmaine put in another query.<br> 11th Feb Mtn store. still no resolution.<br> 15th Feb ref *** mtn 808. said within 3 days would have an email showing me where I supposedly used this data between 21st and 24th Jan. NEEDLESS TO SAY STIL WAITING FOR THIS EMAIL.<br> I want proof of where I used this data because I am paying for a service which I am not getting. I wanted to cancel this contract and was told would have to pay R6800. Not acceptable. CAN SOMEONE PLEASE RESOLVE THIS ISSUE ONCE AND FOR ALL
