Lewis horrible service

I have been such a loyal customer to Lewis stores, bought 2 TV's and on my last month of payment missed a payment and came back to make an arrangement to pay everything I owed within a 2 month period. Lewis loaded a debit order of all that I owed. After I had made my full payment they call me to state that I still owe them interest that they failed to workout on the debit order that I had signed for into settling my debt. I contacted client services and spoke to Chant who than transferred me to Shariesha Williams. I was told that the store needs to write off the account and this was in March 2023. To my surprise they go and debit my account on the 23 September without my consent, taking from my vehicle finance funds. I now have to pay debit order reversals, non-payment fees and interest because of this Lewis who is *********** and debits peoples accounts anytime they feel like and they fail to balance their accounts to provide professional and accurate in formation to their clients. I need my money urgently and I want all these charges to be paid by Lewis, perthitic service and will never shop with this store, they have damaged even my credit score.
