Fail to repair washing machine

I had problems with my washing machine, repair logged. Technician arrived, did his checks. Said motor has to be replaced. This was on 10 Dec '14. So on 15 Dec I called the technician, he said they doing stock take and end of week will get back to me, but nothing and he didnt answer his phone again. So in Jan '15 called service centre, but they keep giving me the run around, keep mixing the technician names around. Now I am being told the technician reported there nothing wrong with the machine. After the 16 Dec talked to Patrecia and was told they getting the part lasted the next week thursday, 21 Dec, yet didnt hear anything. Now they say they have to send a technician out again to assess the machine. Cant get hold of the supervisor, Patrecia, either ignoring my calls or just dont care. LG placed a sticker on the machine there a 10 year warranty, yet as soon as the motor has to be replaced, they just give you the run around.
