Misleading sales

I was called and requested to come in for what i was led to believe was a free service to check my shocks. I did not request a service to be done for wheel alignment. next best thing im being given an amount of R518 that was supposed to pay,mind you i did not ask nor did i want that to be done because i also didnt have money. I had to borrow money to pay this. next time please can the people be made aware that they will be paying for "free" services.
