Overcharged

This is Duma S A ..I found these Michanic people on the net and we agreed for them to service my Volvo and was told to pay R3058 upfront for spares and an hour and half (1.5hrs)of labour

When Philemon their technician or mechanic worked on my car only took an hour (1hr) exactly and I mentioned to him that I've been charged for 1.5hrs

Sent a message to them( Henry)about the time and told him that they owed me R320 for the half hour that I was overcharged for and a girl named Monica came back to me with some lame story about Philemon being professional etc but I don't care whatever is being said it's not about the mechanic it's about the theft of my money that I want back

Again you are saying you don't know the yet they show a thousand stars on their emails about your reviews
