I purchased a niche for my mom Nov 2019. She passed of covid on January 12. Chapel of chimes told me that they had sold my moms niche. I have the deed. They offered another and eventually picked a new one. For weeks I was told that I would receive documents and quit claim to sign. Finally I had to talk to a supervisor on Feb 17 who told me the paperwork was at the main office. My mom arrived at chapel of the chimes on February 12.
When I finally received the documents and had the quit claim notarized I sent them back certified mail. They received them on March 1. I was told when they received them she would be placed. Well called on March 9. Told they are really busy and has not been placed. Then told this week. Well my mom has been there since February 12. This is so upsetting. She needs to be laid to rest. This has been the worst experience during a very hard time losing my mother.
