Bad service from FirstShop (First Technology)

I received bad service from this company. I ordered a printer online on and I provided a delivery address. I contacted the company after 2 days to enquire about the delivery. I was told that there was a problem adding an address to my order but the issue was resolved. The following day the printer was delivered to an incorrect address. The company representative admitted that he unfortunately didn't take note of the address I provided. He said he will correct it. The following day he suggested that I make arrangements for the printer to be collected at the incorrect address. I made those arrangements. The delivery was supposed to take place in the morning, I waited all day until about 15:00. I was told that the courier didn't find anyone by the address & returned with the parcel. I therefore requested a refund on 15 April and I provided my bank details and I was told that my refund is processed and I should expect payment by today. Today I'm told the account department wants my proof of account. I'm surprised why I wasn't told to provide the proof of account when I requested the refund. I don't think I'll ever purchase anything from this company.
