Not supplying the services I am billed for

For the past few months, Vodacom keep on soft locking my account, first in the beginning of the month, after the debit order successfully went of my bank account, and then just before month end. Each time I phoned the call centre in the beginning, they would confirm that my account is up to date, there is no limits, and they would open the line again. The last two times I phoned, there was suddenly a credit limit? All the debit orders goes off successfully, and they even offered and approved an additional data contract, but lock my phone that still have credits of what they billed me for (free call, sms and Data bundle purchased). It is another thing if there are outstanding payments, but there have not been any.<br> <br> I will not renew my contract, and am cancelling the data contract that was supposed to be delivered within 5 working days from 30.04.2015
