Bayport close my account

Am very much ****ed off by the kind of service am receiving from Bayport Financial Services. I had an agreement with them to debit money, they did and I was informed that the money is not appearing on their side a week after the debit date. I then reversed the money back and did an eft payment of the outstanding amount. Now am told I still need to make a further payment for changes which are not explained to me. I have tried communicating with these people but they just won't give me a straight answer. I have recently requested for a paid up letter that has not been done as I am told that I still owe them. I then requested for a settlement letter still it's not provided. I have sent emails and no one bothers to call me or respond to my email except the automated responses. If anyone hears please call me back ***. I really need this account closed asap.
