ABSOLUTELY BLATANT DISREGARD FOR CUSTOMERS AND RIDICULOUS REASONS FOR NOT DEBITING CLIENT ACCOUNT

I have a contract which expires in March2022-ive never missed a payment as my subscription runs of a debit order. i now been listed as 1 month in arears and after several calls have not been assisted and this morning when i spoke to an agent ,i was told i missed a payment because the bank would not allow them to process my debit.Theres is no R/D on my account as i always have surplus to accomodate for errors by the providers.They did do a debit from my account on the 10th of February 2022. What are these providers trying to do .are they trying to ruin customers credit statuses
