The worst service from DEFY

I bought a defy side by side door last year. The fridge started giving me problems and the technician would come through look at the fridge and leave. he did this 4 times last year. I have now been calling defy everyday for 2 weeks and guess what the technician lies and says he has called me. He changes the date as to when he is coming out. I should have bought Samsung. Even their head office is useless. Susan Banda
