Account suspended even though payment was made

A debit order went through on my account on the 4th of January 2016 after the first one bounced. I have contacted my bank and even they said that the payment went through successfully. <br> <br> Last week Friday my account was suspended, I contacted Autopage where the agent advised me that the mistake was one their side and the payment was received. My account was then reopened. Yesterday my account again has been suspended and again I contacted Autopage where they advised me that they have not received my payment. I sent them my transaction history where it shows that the payment went through and it was paid successfully but for some reason they say that the payment was not received on their side. <br> <br> I am still a new client with Autopage as this is my first month with them and I already have problems with them. I am not a happy customer and if this is not sorted out by close of business today I will have no other choice but to cancel my contract with Autopage..
