This has been something going on for so long. Many times, when bikers get over charged, worst still, charged for something that they don't even ask for.
Example, you repair your bike at Shop A, ask to change spark plug. Went for coffee and came back, the mech tells you, i changed engine oil and wash carb for you too cause must do together. Then you've to pay an extra when you don't even ask for the service.
I find that most bikers seems to pay this amount of "overcharged" items or services. Althought not happy, many don't seem to complain to CASE but grumble.
Is it because 1) there's no standard law to control this? 2) Is it because your bike in the bike shop, don't pay them? They take away the parts replace and you've to tow your bike away to another shop + pay them the workmanship fee?
Its about time CASE do up a list to blacklist these kind of shops that's out to cheat bikers.
