They don't even deserve 1*. Wren is not only incompetent but are deliberately out to scam & rip you off. Same as other reviewers here, their salesman measured, 'designed' & sold us our dream kitchen only when it was delivered we found cabinets don't fit where they should & these are ones that cannot be trimmed but they don't care, they just want to make you a large bill & get their commission. They purposely sell & send you surplus stuff you don't need & refuse to take it back, because they 'don't have a refund policy'-how very convenient for them. They send you things you don't need but ironically not give you things you do need. We asked for & were led to believe that we had 2 pull out spice racks but only got 1, this is a ploy to get you to then buy extras & get more money out of you. They will feed you the line, 'we will find a resolution' but don't be fooled, all their 'resolutions' will cost YOU yet more money. If I was an expert & needed to check every last measurement myself, I could have just designed it myself as well, why would I need or want their designer to do it?? You will never get hold of the lying 'designer' after you've paid & signed on the dotted line. They agreed to refund one surplus item, a whole length of unopened worktop we didn't need but they haven't actually managed to get the refund into my account, a month on, 1 excuse after the other. Takes them minutes to take thousands from you but returning a couple of hundred is too much for them to cope with. No doubt my review will be followed by several FAKE 5* reviews so mine moves down & the effect to the overall rating is outweighed. They will be all polite & apologise, feed you the lines they've been trained to do but not actually do anything to help you with issues they've created or reimburse you what they have overcharged or for the inconvenience & upset caused. They will try to wear you down with the 'oh we're so sorry, we will look into it' lines hoping you'll get bored & go away. Luckily I did not use their installers or God knows what I'd be dealing with now. Disgusted with these scammers, they should be ashamed of themselves.
