Many thanks to all who have taken the time to respond to my issue.
Just to add to my issue. In April of this year, I got an email from Santander asking me to contact them. If I did not they would stop my online banking facilities in three weeks time. Obviously I got in touch straight away. And I got interrogated by an annoying customer service person. Asking me various questions about my account dealing in the last 6 months. (in and outs). In February I had to fly back to the UK, as my mother was just about to pass away. I was the executor of my mum's will. But there was no compassion shown in the questioning.
Anyhow I provided all the details I was asked for. Spoke with many different customer service people in the process. Also, I was given the wrong information. Therefore I lodged a complaint process in the way I had been dealt with. complaints dept rang me here. And gave me straightaway 150 pounds into my account for the way they had dealt with me. And was told by customer services the case has now been closed.
Then to find out one month later, my accounts were being closed was a shock.
If they had given me a reason ie living abroad then I could understand, but I have a property and other investments in the UK and I have also paid my taxes on time, as one member pointed out could be an issue. But they will not give a reason of Why, and that is what baffles me. It's like the Nigel Farage case.
Regarding to some messages from you. regarding Wise. yes, I have had an account for the last 2 years. So I am not in dire straits. Also, 1 member stated insurance/annuity companies would not transfer to Wise. I have just had an email from my private pension provider that confirms in sending my pension to my wise account.
Once again thanks to all who responded with various advice
