Customer was charged R630 to a change a fuse

I went to the workshop to see why my electronic seat was not working. I was told the fuse was blown, but before it could be replaced I had to book the car in. The fuse was changed and I received a bill of R630.00.<br> The fuse cost R30 and the balance of R600 was for labour and diagnostics. A job that literally takes less than 5 minutes. I never felt so cheated as I was a customer for over 30 years. I don't think I will ever shop there again.
