No service

Six years ago I requested to change my surname back to my ****en name and app**** for a dual card for my mother. After six years of battling to get this done and a lot of complaining and telephone calls I eventually got it done. During this procedure I submit two e-mail addresses to where they can send my account statements but after four months I still have not received any statement.Phone calls to their customers/accounts/head office do not solve the problem, they are rude and put the phone down in your ear without any results.
