Watch who you buy from

I bought tiles for the whole house. The salesman told me he will organise transport. When goods were delivered they were 5bags of cement short.it was discovered by the driver. He called the store. I spoke to dispetch. He said I must come and collect the 5bags. I told him I want my money back. This was 23rd of November. Even now the dispatch is talking to driver. I have not received my refund
