BE VERY CAREFUL BEFORE ORDERING from SCREEN WITH ENVy Iordered 4 5mm screens from them via their internet page. I then received an email apology for delay in delivery saying that it had not left the warehouse. I then sent them and email to say I wanted to cancel my order as I had ordered the wrong size and would need the 16mm screens. As I had received an customer service action number and no follow up I decided to ring them direct that day to say I wanted to cancel the order as it was the wrong size. And I would reorder the correct sizes. I was told that it would take a long time to get a refund that way and that she could amend the order and send me an invoice to cover the difference. I agreed to this approach. She could not give me the opportunity to pay there and then because I was told the barcodes had changed on the system and it would take her an hour to sort it out! I then received an email to say the screens had been packed and were in the warehouse waiting for the courier to turn up so they said it was too late to amend the order ? And they were going to send them to me anyway!!!! I now have to pay to try and get them sent back to them despite telling them not to send them to me. Reading other reviews it would seem that this company is a difficult company to deal with and almost impossible to get your money back and a refund. It is so disappointing that they have sent me screens that I have told them I do not want as I need a larger size. The customer service person I spoke to this morning about it didn’t want to know other than to tell me that the return would be for me to pick up the cost. The bottom line is I tried to cancel my order before it had even left the warehouse and they ignored that probably because they had my money
