Shocking service from repair department

Middle of December I dropped off my Bosch Grinder and Circular saw at Builders Express in Shelly Beach expecting both to be repaired<br> <br> As I am a contractor I require a fairly quick turnaround time on machines sent for maintenance<br> <br> The first time I had a response from Bosch / Builders was in middle January saying that there was nothing wrong with the grinder ,Even though I specifically stated that the switch on the grinder gets stuck in the on position and doesn't want to disengage( Something that is EXTREMELY dangerous for a grinder that size)<br> <br> The grinder still has this problem. (Their response was that is is supposed to do that) It is supposed to lock in the on position but it is also supposed to disengage once I pull back the switch. <br> This does not happen. <br> <br> I also send in my Brand new circular saw (2 months old)<br> <br> I waited until end of January for the supplier to phone me and tell me I needed proof of purchase for them to fix under warrantee. I supp**** this to them two weeks ago and was then told the machine will be ready and at Builders Express on Monday. It is Tuesday today and the saw still hasnt been delivered to builders express. R100's of diesel spent for nothing.
