Paid my account but line gets cut off

I had a debit order for my account but this unpaid. But on the 3rd i made payments on my account. Today while using my phone, just suddenly it's no longer working. Trying to make a call they say my account was suspended due to non-payment. But i paid in on the 3rd already. So where is my money and why was it not allocated to my account. This is unacceptable service. I paid my account. I want my line reconnected ASAP or my money back.
