I have several bank accounts and open and close many.

I have several bank accounts and open and close many. the only reason being interest rate changes. there are many accounts that offer good terms only to lower interest rate after year. I close and move on. However my account with cynergy is the only one that has survived in fact since it was called the bank of Cyprus. So well done. Reviewed on: 17th April 2026
