Unsatisfied and angry customer

What a terrible service I have experienced at miladys i always pay my account on time i usually go and pay at branches but because of covid 19 i was paying online my account was not updated on time payments went missing on my statement I sent through emails with no response and what worse I lost 20 points on credit bereau because miladys said I did not pay I think miladys has incompetence and inefficient staff and will definitely close my account with them because customer service is not a priority
