Bad service

Asked me to pay upfront R450 for a call out. I paid it during the morning as an immediate payment as requested by Jason the owner. He made appointment for 12 o clock. Then he send me a message he has probleem with his fone he would come 8 am next day. Next morning he send message he can only come at 12 again. I advised him I have a wedding venue and need my fridge fixed. He said he would definitely be there. I tried to phone him at 1 pm. No answer. Doesn't read my messages. Bad service and *****ing money.
