On 10th August 2009, I sent in my Canon 28 mm f/1.8 USM (Warranty still valid) to Canon Service Centre for non-working autofocus.
After several about a week of waiting, I was then told that the parts would not arrive in time for their previous promised date of 26th August, and they loaned me a 17-35 mm f/2.8L to use for the time being.
As of now, 16th of September, I have finally received my lens... however after checking by both myself and CSC staff, it happens that the lens is now suffering from a obvious back-focusing issue. I then told the 1st staff (young female) that I need the lens by Monday, 21st September. I also had to send in the body to be focus-checked with the lens.
A 2nd staff (moustached man) then said that the cost of the "express service" for the lens/body to be ready by this friday (monday not possible due to hari raya) was the full $40 as it was within an effective 2 working days. Until further negotiation and argument, he decided to give me the express service at a special rate of $25 (Usual-rate for 3-day express service).
1. Total time taken to fix the lens was a gross 36 days.
2. Was told initially that the lens would be calibrated precisely.
3. Was told that the lens was not calibrated in anyway by the first female attendant. "Only parts were replaced, no calibration was done".
Moustached Man's arguments;
1. Calibration of the lens-to-body and body-to-lens is a different procedure. All lenses are calibrated to a CSC standard body.
This contradicts the "Only parts were replaced, no calibration was done statement."
2. The procedure of the lens repair and post-repair calibration are seperate services and the calibration would be tentamount to the standard 5 working days agreement.
Basically, I don't think I should pay the $25. Nor do i think I should wait any longer for the service to be complete.
Since both sides IMHO have valid reasoning, what should i do?
