Faulty Dishwasher - Service centre not responding

I bought a new dishwasher in December and have used it twice as the first time I opened the dishwasher and there was still water in the bottom that had not been pumped out. I checked the filter, checked the hoses all was good. Tried it again and same thing happened. <br> <br> I phoned the service centre, what a joke!! I was told the technician would phone with in 48 hours to confirm the time and day they would come. Plus on top of that I must pay a call out fee!!!! Even though it is under guarantee!! I advised the lady that someone can only come on a Friday between 8 and 12 or on the weekend. She advised that I must discuss this with the technician when he phones me. 3 days later no phone call. I phoned back, gave my story and was put on hold while the lady phoned the technician. She came back and said the technician will phone you shortly to confirm time for tomorrow( Friday 29/01/16) this was at 3pm still no phone call. <br> <br> I think it is unacceptable that a new product does not work correctly, but even more of a shock is that no one is interested in helping and that I must pay a call out fee to have it fixed under guarantee!!<br> <br> I hope this matter gets resolved!
