Michanic the worst mobile mechanic in SA.

My sister's car stucked on the 19th December 2023. We contacted Ford and they said, they can only book it on the week of 27th December 2023 we resorted to Google find Michanic with good reviews we decided to try them they responded very quick sent mechanic to check the car and he said the car is not responding to diagnostic machine. He e sent report to the company that computer box needs to be tested. They sent quotation we agreed and payed the said amount. The following day on the 21st December my sister called them and asked when are they going to collect computer box for testing and they said where they test computer box is closed until the 3rd January 2024. Then my sister asked for refund and they said they will check another company then they sent mechanic to collect it and they said it will be back the following day. They close for festive with our computer box without saying a word. They opened on the 2nd January according to the mechanic but still they remained quiet. My sister called them everyday they were even dropping calls as soon as they hear the name Dorah. O the 5th January they decided to return computer box with no report and job card for the mechanic to fix it to the car. We had to lock the gate and told the mechanic that we are confiscating Michanic car until they take us serious and refund us. We fought to get the so called report over the phone. Until they realize we are not bluffing we really meant business when we say no refund the fate remains locked. Then they refund us and we release their car. Their own mechanic said this is happening for the second time and he always court in the middle. Poor customer service, they run business like ****a shop.
