LG Dishwasher poor service

After reporting a problem with my dishwasher October 2017, I was informed that I have to pay R650 before a technician will come to my house, but it includes all trips they will have to make regarding this call out. After paying, they came out - made the diagnosis - and I had to pay for the new part in advance before they would install it. I paid and after two weeks they came to replace the part. When they tested the machine - the old problem was still the issue. They then established the mice was the reason for the problem. I kept the old part as I was sure that is was not necessary to replace it.

I again had to pay for the wiring of the machine to be replaced in advance. They came out again (when I was not at home) and replaced the wiring. When I got home . . . the machine was still not working and the previous part which I kept, was missing, which means that they took it with them.

After contacting LG again, I was informed that they have to replace another part as well and . . . I have to pay for it in advance. By now, the call out fee and all the parts I had to pay for, is almost R3000.00. (I could just as well have bought a new dishwasher!)

The part is STILL NOT REPLACED! First they had to wait for it, as they had to order it from Dubai. Then it was December and all factories were closed. It is March 2018 (6 months later) already and nothing - even after I was told that they now have the part. The lady (Jeanette - Pretoria North) I deal with told me the last time that somebody from management will contact me but I haven't heard anything from them!

This is very poor service delivery! What can I do to get helped? Please help!
