Poor service. Broken machine

I am utterly disappointed in Bosch. I have been dealing with you guys since jul last year trying to sort out my appliances,which i paid cash for. First it was my stove and now my washing machine. After numerous of calls and complaints, to date nothing was done. Only promises to call back was diligently and effectively done. My needs were not met PERIOD! from the tech not working after 4(tech replaced my motherboard after 5 prior to this) to all the follow ups. Nothing. Imagine having to do washing manually in an auto machine, whats the point of having one? The audacity to call me am say i must pay im extra money cause they don't have this model. How is this my faulr. I've been using this machine for 9 months.. You sold me an factory faulty machine now i must pay. Why must i suffer? Why must i settle for less? Why must i settle for lose parts tp a brand new machine i bought. I should have stuck with SAMSUNG. Not once have i called them for my fridge and i bought all three appliances at the same time I could have saved myself lots of stress, drama, back aches, and manicures. I shouldn't be paying in extra for a new model. You should have sold me a new machine. I dont want extra parts. I want my refund with a voucher or n new machine. Very upset
