I’ve just received a bill from the managing agents for my flat saying I owe over £700 in service charges. I queried it as I always pay on time by Direct Debit but they claim it is from many years ago when they were changing companies /between systems. I can’t pay them the full amount at once so will have to pay monthly ,which I am sure they won’t be happy with, but to be honest I think they have a bit of a cheek only mentioning it now? Surely there should be some sort of time limit. I do know I will have to pay otherwise I would breach my lease agreement but it is frustrating! WWYD?
