The telephone number 8889762972 is being used as part of a scam in which a postcard is sent out imitating the Cecilian Bank. This correspondence is not from the bank it is sent by scammers.
The postcard includes a warning that a mortgage account with Cecilian Bank has been closed down. It urges customers to phone 888-976-2972 to discuss the loan. Do not phone the number, it is a scam. Throw the postcard in the bin, and get on with your life.
