Housing association sorry for service charge error

A housing association has apologised after it sent rent and service charge notices to a group of residents in north-east London with cost increases - some of which were more than 50% - "in error".
Notting Hill Genesis Housing Association said it mistakenly "included the previous year's service charge costs" and it was writing to residents to clarify the situation.
It comes after residents of Duke House - a block of 15 flats in Hackney - ed the BBC to express their frustration.
Krystall Brown, one of the residents, said the notices were sent out in September and the first payment was due on Monday. She said it was "unacceptable" that the error had only just been identified.
"They had enough time to look into something like this, they sent out the letters in September, it's now April and it took us to make a complaint and to go to the BBC to get them to have a look at this," she said.
"If we didn't make a complaint, when were they going to recognise that they had made a mistake":[]}
