Review Very very bad service

I've bought a new washing machine from ok and it broke took it back as it is under warranty they fix it and it broke again now this happened 3 times already so I decided to exchange it for a more expensive one got by the shop and they said there's no stock at the moment but they were advertising it they made me understand as soon as they get stock they will call me it's almost 2 months now and finally this week they got stock came to collect my machine and they told me that's customers stuff I must collect mine from the warehouse isn't it there job to ensure that my order was there with the others
