Terrible service from RCS/Makro

Hello

I have a Makro/RCS account, In October they phoned me as my debit order bounced, think it could be as i have a new bank card, So made the arrangements and i the full amount for my arrears and balance was deducted by debit order on the end of October, So on the 5th of November i emailed the RCS/Makrp group and phoned, on the 7th November they said my debit order was received. Now they phone me, It apparently bounced, so after 7 days according to them it bounced. Spoke to a guy this morning, telling me i am in arrears but they received my payment last month, so now i am asking how can i be in arrears if i pay every month? He is not able to answers my questin and will get back to me. He keeps telling my payment was revceived last month and on the 30/12/2021 ythe debit order for Decmeber will go off, But i am in arrears. I do not understand how this works.

Not to mention you email them and get respone a week later, they phone you and the phone cuts off and they dont even bother calling you back
