Very disappointed customer

Iv been using finchoice for a while now and never had any issues with them and my payments were always on time never missed never had debit problems now December they decided to debit earlier even when I told them not to thus resulting in my account being late I then logged on the app to arrange the payment date for the next debit order which was the 29th December they only debited 3 of my products I have with them and claimed my bank account didn't have enough funds for the 4th one which was strange because there was more than enough money in there for the debit. I then called and the consultant gave me the banking details for eft which I did. When I checked my bank account a few days later they debited luckily it did not go through. I sent numerous emails called many times up until today where they said the mo ey I eft.d was allocated to wrong account and that they will fix it and my app will update and funds available for withdrawal will be seen. It's been a few hours and when I check my app still says that all my products haven't received any payments and that I must make a payment arrangement. I chatted to the social media Consultant as by this time I exhausted all my airtime and she advised that I don't have any funds available or qualify for anything based on my payment record but how was it my fault iv gone through the ends of the earth just to get it paid on time o ly to be told I don't qualify for any funds when I was depending on it to get me through the month atleast. I'm very disappointed at this point I just feel I want to pay my products done and never use them again
