Verimark Genesis 10 in 1

I am wanting to find out how to further my complaint with Verimark. I purchased a Genesis 10 in 1 steam mop in Feb 2020. After a month its stopped working- I had only used it once for one room. I then took it back where they took my proof of purchase (slip) and immediately replaced it with a new one. I then used the new machine and once again after using it on my kitchen floor, the machine stopped steaming. I then took it back to the store in Baywest PE and they asked me for my slip. I then told them I gave it to them with my last machine. We went through returns book and found my slip. This time they said my machine needs to be checked by their repairs department. They told me 1 month and after 6 weeks no response. From June until August I had not heard from them. I then went in to ask and the 2 sales ladies mentioned that they did not have any stock. Obviously meaning they were going to replace this machine again. I went in this week to be given a new machine but this time no slip and told my guarantee is only valid for the last few months (from my first purchase). They told me I must use my bank statement as proof of purchase.

I have not opened the new machine as I would actually prefer a refund on this product.

The service and products have not been up to standard and do not feel like going through this process again.

If you could please clarify where to go from here.
