Terrible service from Onsite Appliance Repairs

I got the worst service from this company onsite Appliance Repairs. They fixed my washing machine at the end of October and I experienced problems the next month. I have been calling them and they have been promising to come and assist me but never showed up until today. I feel like I wasted R3300 for nothing even though I was promised 6 months guarantee. Be careful people, I do not want to see you in the same position as I am.
