Merrill Lynch review: Customer service for customer residing in UK

account number 7CR-13147
I have been trying to contact regarding shares I hold on the above account. I am unable to log in and because my email address has changed I cannot reset the password. I have written letters and tried to call all to no avail. All I want to do is sell the shares and close the account, I no longer work for First Data and have retired some time ago.
I just want someone to help me get this closed. My telephone number is [protected]
