BAD SERVICE AND **********

Phoned Cell c to query my data bundles and the lady who answered gave told me that I used data as per below. 03 February 15mb and 1mb, 04 February 322mb, 07 Feb 502mb and 100mb. Thereafter I realised that the 7th was on Sunday and I called back CllC and spokre to Keshni whom he gave me different information from the one I received earlier - 6 Feb used 361mb, 7 Feb - 100mb and 09 Feb 502mb. I think there's something fishy here bcos I've asked to be transferred to the manager and he refused? May I please get responce on this matter otherwise I'll have to take it further. I also asked to cancel my contract and he said I cant as I only opened my contract last year (not true bcos my contract for more than three years) surprisingly he even said I need to pay R500 at the end of the month - what the....?
