On the 18th of June I sent my bike driver for bike spare key, it was around 8am. They made the key and he paid R250, before they've finished they noticed that there was a ***** missing, they looked and didn't find it, they then replaced it free because it was their fault. He left the shop and rushed to work, after sometime he noticed the noise on the fuel tank, he checked and only to find out that the ***** was careless left inside the tank. I phoned them to report the matter but they said they don't have someone to go and fix the problem, I asked the estimate time maybe then they said they don't know, how can the manager fail to give me estimates because the driver was waiting for them instead of working, how can the manager failed to solve the problem? Management skills? Damage control? After a long argument he said they'll phone me before they close so that I'll send driver's location to solve the matter.
