Suspended my lines even when paid.

My debit order failed on the 30th of November and then the following day which was the 1st of December I went to the store and paid the money in cash at the store. Yesterday I woke up and all 7 of my contract lines was suspended 7 days later. And show that my account is in arrears with 30 days. I had to go from store to store for assistance as it was loadshedding in my area and my wife needed her phone to be on 24/7.After the store switched my lines back on they could see my payment. Why am I 30 days in arrears when my account is up to date. I had to send my proof of payments to complaints and I still did not even received feedback from them either. My big thing is why am I in arrears when my account was always paid?
