Billing

My account has been suspended. My current balance is R1600, normally my account is between R500-R700. The explanation is that I am being charged out of bundle rates however I have had data bundle credit the whole time which I even confirmed yesterday and as a precautionary measure topped up with extra data this morning. Why is data usage not being deducted from my data bundle? Spent 2 hours on the phone with customer service and a call has not even been logged! According to the supervisor a call can only be logged after the account has closed for the month. It is completely unacceptable that nobody can assist me or give me an answer to my query which impacts me financially. The account was taken off hold however I was told the billing might continue as it is currently. I will expect a phone call and a reference number as soon as possible.
