I am somewhat perplexed with the difficulty I have had with trying to access my account – Stuart Gulliver email address

Daphne sent a message to Stuart Gulliver Group CEO, HSBC Holdings PLC – email address that said:
Dear Sir
I am somewhat perplexed with the difficulty I have had with trying to access my account using my bank card and pin no. In fact it is beginning to evolve into a saga!
I requested my pin number to be sent to me. I received the pin number and when I tried to use it I received a error message. I asked for help at the Sutton Coldfield Birmingham Branch and the Cashier tried to access my account using the pin number and the card. No success. She suggested it may be a problem with my current card and requested a new card to be sent. I received this today 1/9/2016 and again tried to use it at the cash point at the same Hsbc branch. No success. I asked advice of the Hsbc 'Front of House' gentleman and after much investigation and re-checking, etc, etc, No success yet again? I was told to contact 'lost and stolen, and to say I had lost the card, which I did and rather than tell a lie I explained every thing yet again? I now have a new card and new Pin number scheduled for delivery - card to the Branch (Sutton Coldfield) at my request and pin to home address. However when advising the Branch address The postcode on the Internet is B72 1PL but on HSBC system it is B72 1PD which is the Gracecgurch Shopping Centre (Royal Mail)? I was beginning to get more and more concerned re:- Misinformation/Security Breach. Your staff (Janice and Hazel) called me from 'lost and stolen' and said that they have looked into the problem and said that there must be a problem with the new bank card that was sent to me and also the current bank card that I already had? Totally confused. Confidence in HSBC failing fast. I would welcome your input.
Regards
Daphne
