Shocking service, no apology and being called a liar

Shocking service, I bought kitchen cupboards there and as the doors were not in stock, although i paid for them was promised a phone call within a week. Three weeks later no phone call went in and spoke to the manager who showed he did not care less, told us to talk to the department after waiting 14 minutes spoke to head of department who implied we were liars as they had phoned, they would not look at my husbands list of missed calls on his phone just said they had phoned, so not even an apology. I was planning to buy a whole new kitchen from them but will never deal with them again
