Bad experiiance still unresolved after 3months

Since March we have been trying to change our email addresswith this company to date we have been failed. My wife and mysel are computer challenged and have no scanner . Yet we reieved very little help or sypathy from this Co . They require a form to be filled in and returned to them. In lockdown this was not possible as we are house bound .and without postal services . We have several other investments with other companies who gladly changed our email. This company does rarley return phone calls treats the elderly with contempt and displays an almost angry responce . Please think carefully before entering into any investment as you will regret it
