Appliance Repair Cape Town - Ripped me off

i made use of appliance repair cape town a few weeks ago on a saturday to fix my gas hob, where no gas was coming out of all 4 burners. i was quoted approx R 250 for the callout and R450 per hour for the work The service was good at first they responded and came out promptly,

3 people arrived a hour or two later - and they got straight to work, however when the completed the job, they asked me to confirm the issue was resolved,

They packed up and then one person remained to do the payment with me He then says to me " you do know the part he used is just over R900 each". the part is a small ***** called a "nipple" that allows the gas to come out. he said that he had to replace all 4 and that i now owe him R5500.

i questioned him an the price and he made me believe there was no alternative to replacing these *****s and that the price is what they cost, and that he was doing me a favour for replacing the regulator as well free of charge. i also dont believe the *****s were new - he took them out of a bottle with used spare *****s, nuts, bolts etc.

i felt i had no option but to accept.but after they left my husband advised me that an entire new hob was selling at R5000.

i called the person i arranged the callout with and said that i would prefer that the parts be removed and replaced with my old parts as we now realized we were **********. he said he was unable to get hold of them and he would revert on monday.

On monday, he said that there was nothing he could do as i accepted the price., and said the technician quoted me before the work was done. Which he did not do. I asked him to either bill me correctly and refund the difference, or revert the repair and refund me completely. After a long debate - he agreed to speak to the owner of the business and revert. I am yet to hear from them again and they are not responding to me messages or emails. Please be careful of these people - they are not upfront with their pricing and i believe they took me for a ride
