Similar story happend to me. Tried to open an account and was first refused. When i called the helpline the IG rep was very unhelpful and could not explain why my account was refused, simply said you need to have a minimum amount bur refused to say what it was. When i said my funds would not come only from my savings but from my husband ones and we would like to maximise the ISA allowande between the 2 of us he suggested i should reapply.
after reaplying my account is now pending activation for 5 days while they review my docs (passport and utility bill). At this rate the tax year will end before i’m able to use this year ISA allowance. No one seems to get back to me on the chat support.
so far not impressed with the customer service. I’m trying to be patient but really...
