They have ****** our money

I ordered a fireplace and paid an 80% deposit on 4 April. The lead time on the quote is 7-14 days. It has now been over 6 weeks. Every time installation is scheduled I get an excuse last minute - from missing parts, to weather to car accidents. I have spent my life savings to get a fireplace for my daughter’s health and we are now deep into winter with no fireplace.
