this is a bit of a catch 22. You are a member of the management company. ..you pay your fees which is your contribution to all the costs of running the management company, in laymans terms you are essentially paying pro-spectively for services to be be provided rather than retro-spectively ...this is why when buying an apt from new you have to pay charges up front in most cases before you are given the keys. You should make it your business to find out the financial circumstances of your company. , It could be case that the services have not been performed because you are not only person to not have paid fees and therefore there is no money to pay for them. (the management company that i am a member of, have found ourselves in this situation) I am not defending the management agent ,who normally look after the day to day running of the company - they could be doing a shambolic job, in which case the route is as a previous poster has suggested , talk to the directors / residents, make enough noise and try to go get the agent sacked.
In answer to your original question ...in most cases you can come to an arrangement with the managment agent to pay all debts owed over a defined period of time normally before the end of your company's financial year, however this depends on the company financial position, they way not be a position to extend the option of staged payment.
