2 days ago I was locked out of my online account as I was attempting to transfer a large amount over several days to an ISA and their security department stopped the last transfer - OK so far. I called them on the number advised by SMS and waited 30 mins - decided to try again in office hours. Waited 10mins on the security number and decided to try again via my ‘select’ direct line -waited on that line for 20 mins and when eventually answered they had to transfer me to the security department to unlock my account and I waited another 40 mins for an answer. Sorted eventually until yesterday evening I got another security message stating they had stopped a transaction due to lack of funds - checked online and all appeared - all transfers had been honoured and I was in credit. Concerned this could be a scam or error - tried today to contact via ‘select’ - gave up after waiting 30 mins. Circa 2 hours wasted waiting for them to answer altogether!
