Kindly ask Sentinel to contact me?

My employment was terminated 11 years ago, but I am still a member of Sentinel. although I have contacted them over the years to change my details up until today I have to contact a branch ( if they pick up) and request a statement. Once again I sent emails, tried the webpage to log on , called the help desk, etc. Will you be so kind to ask Sentinel to contact me, perhaps they will be courteous enough to respond to your request?
