If you can leave this bank we definitely getting our business out

They mistakenly put a default on my husband’s name , been trying to sort it out for two months , they have the paid up letter of the home loan we had with them and now they are also the ones declining us for the new house we trying to buy . They were very fast at putting the default without even verifying now we need to wait 6 months for something that shouldn’t have been there to be removed
