Business ProfileforSierra Central Credit Union

In December of last year, I took out a consumer loan with my branch. Its Sierra Central Credit Union to pay off credit card debt. The stipulation from them in order to prove the loan was at their office distribute the checks to creditors. On December 21, they issued check number ***** in the amount of $501.20 to pay off my Amazon account. However, instead of sending the check to ************** who holds the note, they sent it directly to ****** in ******* **********. This was a grave error because Now the check is gone. Upon learning that the check was missing and ************** had not The recipient of the check I contacted ******************* at my branch to get the situation rectified. Initially they gave me information on the tracking, etc. for the check, but that still does not take care of the fact that it was sent to the wrong place. The check was cashed or deposited at a ***** ********** and ********, ********** for Amazon. I have copies of, the check and all the information. Amazon will not help me and my bank refuses to help me and yet here I am already paid back the loan and still out the $500. This is not OK. Subsequently Ive emailed ******************* several times but she just ignores my emails. Amazon, I have talked to so many different people there in so many departments for an hour or more and nobody is helping me there. The ***** Fargo in ************************* will not work with me because I dont have an account. Where is my money! I want my money, returned to me. This is no way for a financial institution to treat their customers. Especially when the error was on their part. Its as if everybody wants me to just forget about it and go away. Please advise as soon as possible. Thank you.
