Incompetence

I hit 1 because there’s nothing lower. Following the previous review I can state that nothing has changed. I’ve now offered the assistance of a grade 4 leaner to help them calculate the following: Amount owed for the period January 2023 through September 2023 versus the amount paid for the same period. It’s taken more than a week and I have still to hear from them, it’s seriously pathetic that a company with an accounting department cannot work this out. I’ve also asked them how I claim all the bank charges for reversing the DB , doing an eft (my wife does that) then withdrawing the money to pay her back. Again no response. Is there an ombudsman this can be taken up with???
