Poor service

With reference to MRP ********** I have a deduction order that goes through every month to pay for data. Since June 2017 I have been blocked and did not get to use the data. I sent a mail to mrp help to assist me to resolve the problem but was notified I should work through the help number. So I tried it again. Every time they just inform me my account is in arrears and they cannot unblock my service. Every time I ask them to explain how it is possible for me to be in arrears if the money is deducted from my account? Yet up to today 04/09/2017 I have no access to the data and no assistance. So every month I pay but do not get to use the data. Thembisile Tembe and Fathima Allie did not help me but just left me to struggle on my own. Even when I asked to terminate the contract I was told to first settle the account. I am at wits end. PLEASE SOMEONE HELP ME
