Missed Debit Order

Hello Peter, I have an issue infact I'm utter disgusted by the service of connect fin on behalf of Bradlows, when I opened an account with Bradlows this year April, I suggested that they debit on my account on the 1st of every month. however, they were not doing that, they will debit as in they feel and that has resulted in their system missing my July payment on their side. I have sent them numerous proofs of payment (Bank Statements) with proof that I have not missed any payment as my money goes out for their debit. now my credit score is messed up... these are the dates that they debited, it not consistent they do as they please. on the 29th of April 2022. 01 June 2022. 01 July 2022., 29 July 2022, 31 August 2022. I don't know what to do now, because I will send my proofs of payments and I will receive a SMS that my complaint has been resolved and then again today 11October a lady called me that my account is behind like really?
