Increased invoice on a single service

Ozvaldo

We have owned a flat in a purpose built building consisting of 12 flats for the past 9 years and have had nothing but problems with management companies dealing with services,
Our latest issue is that each flat had been issued an invoice to be paid for management services this charge was paid in full in the allocated time but now 3 months on we have been sent a second invoice for the same service upon contact we have been notified that it's because the first invoice did not cover the cost and the management company went over on there origanal budget!
Is this this legal in anyway?? As it feels like we are being charged for somebody else's miss calculations.

This may be better transferred to the house buying and selling board which frequently has threads regarding service charges.
