Need some advice really DWP phoned me and said I have 2 ISA accounts with Halifax and virgin money I don't have any accounts with the above banks .I've contacted the banks and they confirmed I don't have these but can't issue a letter confirming this as I'm not a customer .I've explained this to DWP but it's down to me to prove I don't have these accounts really at a loss as what to do ,I'm a single parent with 3 kids which is hard enough as my daughter is disabled this is causing me untold stress and worry
