Pathetic Lack of Service

My partner and I went to view a fireplace on 15 June 2020, we were super excited and were ready to make the purchase that day. When we arrived we received a cold reception from the lady in the office and we were offered assistance by the older gentleman. He took us to the workshop to choose the fireplace we wanted. When we returned to the office and asked the lady's advice on the shape, she said "we must decide as we're going to be living with it!" She told us to send an email to place the order and she will provide an invoice for payment. I did this on 17 June 2020. After 2 hours no on responded to the email so I called to ask if she had received it and she said they are busy and will get to it when they have time, I should wait. Up until now no one has bothered to respond to my email or message I sent Sean Greyling on Facebook messenger. Clearly they don't need the business during these tough times!
