Western Union

My aunt purchased a money order from Western Union to pay her rent. Spilled coffee on it and had to send it to Western Union for a reimbursement. Mind you this was early November!!! Western Union claimed they had sent the check out multiple times and gave her the run around. She received the check yesterday- Jan. 10, 2020. Took it to the bank it was drawn on and Wells Fargo said it is only good for deposit???? She gave them cash for her money order. She does not have an account to depositor into!!! Not using Western Union again!!!
