beko Din28x20 Dishwasher 1 wash it STOPS & careplan is

Currys in Cambridge UK bought a Beko dishwasher with (stupid me added "CARE"!) I & my wife late 70's & both in poor health! The machine did one wash! & Poorly! We called "care" in 7 days an expert turned up! From Beko Via Currys! Looked at it tested it "it's not working" needs a new PCB & I'll bring a pump! 7 days he came back, couldn't find where the PCB went took off all the panels, finally it was found underneath! Broke the PCB fixings and failed to fix the water pump 2 hours he went still not fixed! BUT as he stripped off every thing it was obvious the 2 "expert installers" fitted the door wrong ignoring the simple to use template with the sticky tabs & idiot instructions! They also didn't fit the legs, & the top machine tabs & screws! This is despite there being a 4 min video on Bekos web site showing how to do it by a young girl & a man!
It's now nearly 13 weeks STILL nothing sorted! NOTHING!
This is the 21st Century!! & I need a new washing up bowl!
& remember Currys shunt you from a "press" a number roulette game to hang up! OR Go away people we have your cash!
(I almost said they treated me like a shunt) Sad I worked once in retail! For the companies forerunner Dixon's! service then was quick & sorted! In Bond Street!
Oh! I have the pictures & video! and a calendar!
Come on Currys for god's sake help 2, 76 year olds! Your "care team" along with Beko have full details photos, of the damage cased by your installers who couldn't
be bothered to spend the 4 mins on Bekos web site for instructions very simple! NEVER even read the install booklet, to fit the door! now damaged door.
or the top fixing brackets, floor levelling feet as all the bits were left in a pile on the work top! they also left an "installation certification" for another person
(same village though! different address & postcode!!)

I think I covered most of the points till I was labelled as some sort of leper! (there is a leper church in Cambridge!)
