Cell C data sham!

After declining to renew/upgrade a laptop and data contract, I opted for a month to month top-up data only deal for R99 monthly. The consultant never loaded it as a top up but rather an open line. This I found out after querying why the debited amount was far above the R99 subscription amount. I reported/queried this two months in a row and neither time the issue was corrected even after being told so. The following month CellC debited the incorrect amount again and this time I had not even used the data sim at all that month. Add to this, additional separate debits from CellC are going off from my account, for which there has been NO agreement or authorisation. This is incredibly poor service from CellC!! And even though I've had a cellphone contract with CellC for many years, I will definitely not be renewing it in the coming months.
