Synchrony Bank Mortgage Complaint

Synchrony Bank Mortgage department,

Conventional fixed mortgage Loan servicing, payments, escrow account California

We Re-Financed our Mortgage with a Credit Union, with Cash Back to Payoff Creditors. Our Credit Union used a Title Company to perform Creditor Payoffs. All but one Creditor received Payments. This Title Company has documentation they have sent two Payments, first to the regular Payment P.O. Box on Billing Statements. After 19 Days, Title Company said it was never cashed and Voided it. A second Payment was sent Overnight - to a Payment Center at different street Address, Delivery received in person, yet after 8 Days has not been cashed or Posted to our Account. Our efforts to solve this are ignored by Collections & Customer Service. Our Credit Union & their Title Company are willing to again Void the Second Payment Check and issue a Third, but recommend a Manager Name, Telephone with Street Address for - Tracking Delivery Verification, which the Creditor will not provide. Should we send the Third Payment to the same P.O. Box without ability to Track or document what happened to these Payments?
