Bad service from bayport financial services

Late last month i had a conversation with 2 bayport consultant about arrangements in terms of payment, i told them that i am working only 2weeks in a month and so i will only be able to pay twice a month, they said they will keep calling once after 2weeks to make arrangements for other week's so that they minimize the bank charges for me.but to my surprise they went to debit my account on Tuesday 6October 2020 instead of Thursday 8 October 2020, the money they debited was for my bond repayment as my 3month holiday relief by the bank came to an end. I have made arrangements with all my creditors but bayport financial services is really torturing me, i need legal assistance with a financial or financial oumbatsman
