********* & Unprofessional Serving Clients Despite Of Payment

i have read the complaints and this is exactly the poor and ********* service i received. I have made arrangements and followed through on payment just to be served the following month. When i enquired this with the MBD i was told that they did not receive in 31 days last payment received was 25/01/2022. I received the documents served before the 25/02/2022. My arrangement was for every 25th of the month, They could not assist me with any response after this. I have asked for a senior's details or for them to get back to me to take the matter further, To date no responses, i have sent three emails since to find out a way forward and they refuse to respond. How can a company that represents an entity as big as a bank be so ********* and unprofessional . Is there any attorney or collections board that we can report this company to?
