terrible after sales service, 2 months still no help

my washing machine door lock packed up, technicians came out promptly to asses on the 26 October, parts were supposedly ordered, 6 weeks later with multiple phone calls and emails, parts still hadn't arrived, parts eventually arrived technicians came replaced all the parts and machine still doesn't work, it is now the 20th December, nearly 2 months later and still no progress, completely un acceptable, 2 months now that I must send my clothing to a laundromat. it is now Christmas shut down and will be at least another month before anything happens, I phone daily and email often, each time you speak to a consultant, then it needs to be emailed and escalated, I am now tired of it being escalated. I am ready to drop the machine off at my nearest Makro store and be done with it, I am done!! completely over it tired of people not being able to do their jobs, never once received any feed back, I as the paying customer must always phone to put pressure
