Conventional fixed mortgage Loan servicing, payments, escrow account Florida

Our Loan was recently transfered from - to - which we received notification for in -, We made 2 payments to - and when we went to Pay for - 2016 their web site stated there was no payment due, Today I was finally able to get thru to them and they stated that they had sold the loan to BSI Financial Services, I asked when they where going to let me know and they said they send a letter, I told them I never received a letter so they looked it up and found out that they had put the wrong address on the letter, so they are resenting another letter today, I have not received anything from BSI as of yet. I am in hour - on hold awaiting a customer service rep for BSI to track down some information so that I can pay on my mortgage. Do I have any rights here or will there confusion cost me more money?
