Mazda 5 - 2006 - Window Power Switch - Hacksaw

Can open drivers window and one other window from drivers controls (Although could only open drivers window when bought?) Garage I bought car from a month ago has sent a new switch which has been fitted but still doesn't open the two other windows. The passenger’s windows do operate from their own switches.

I have heard this is a common fault and their may be a work around?

Thanks
