I joined when they were my local credit union. As a CU, they were tops. As NY Community Bank, they were the worst.
The worst of the worst-- they failed to pay my mortgage to Wells Fargo. They claimed I wasn't authorized to pay my mortgage electronically, though I had done so for a decade. Had a 3-way conference call with NY Comm Bank, Wells, and me so Wells would hear the BS for themselves. After the phone call, Wells said they'd waive all late fees, charges and so on (due to NY Comm Bank's failure to transfer money), mail Wells a check and change banks.
There's more, but I won't bore you.
They don't have any flexibility and rude. Worst bank to deal with. They don't know how to do good to customers. I didn't intend to do mortgage with them, but they bought off my mortgage. However, they are surely one of the worst bank in the world. Oh, btw, their online system sucks in foreign access and the website is like from technology of 80s.
