Overcharged commission

A call out to other property owners to ALWAYS check your commission being charged by Booking.com

We have been overcharged commission by 3% extra and I've reported twice to Booking.com

Their response is 'there's a bug in the system, we will fix it', but we can't tell you when

I am so annoyed and disappointed at this

Calling out to all owners - check each reservation with the commission

Problem is still unresolved
