Mechanic in Motion - BEWARE!

Warning! Do not make use of Mechanic in Motion. They came to my house to fit a sensor and they misplaced the lock nut which could happen to anyone. The owner Linda is extremely RUDE and told me how can i accuse them of misplacing the lock nut. As misplacing of something can happen to anyone! Now i need to replace the lock nut myself. Now the mechanic is saying he never charged me for taking of the wheel and showing my son how to put in the new sensor, he said the call out fee was R375 and i said its strange Linda quoted me R250. Now they are saying we did not charge you for the call out fee so you can pay your own lock nut! Just be careful when using Mechanics in motion you might be disappointing with a service that was once VERY GOOD before it got sold!
