Poor service

My boyfriend received a call from a call center agent at Blake last night saying that they have not received payment for his account since the 3rd of June 2015. However he receives an sms from his bank every week when his account is debited. He has also collected a statement at the bank and all the debit orders to Blake are reflected. Can someone please contact him so that this matter can be resolved. This seems very *****, clearly someone at Blake is not doing their job properly.
