Information not being updated

My signature is not being saved onto system, it’s frustrating & time consuming to update every time I go to the bank to do something, I have been to Pavilion branch to collect my new credit card in Sep 16, was told that my signature has changed & I updated it, in Feb/Mar 17 went to this branch to pick up a new debit card, I faced the same problem, they could not find my updated signature done in Sep 16 & I update it again, in May 17 I went to cancel a Contract Save account that matured, again they could not pick up my signature updated in Sep 16 or in Feb/Mar 17, I updated it again, went to the bank a week later to find out why do I have to keep updating my signature every time I do something, why is it not being saved, I was assured it was on the system since Sep 16 & that the previous consultant should have picked it up & I won’t have this problem again, I went to the bank on 6 Nov 17 to collect my renewal credit card, I faced the same problem, my signature is not updated on the system, they cannot pick up the update done in Sep 16, Feb/Mar 17 or May 17. It takes time to wait in ques, time to sort out whatever I went to sort out and then more time to update signature. I’m charged a lot on bank fees and other charges but the processes cannot be made simple and my updated records are not being saved. I still have to go back to pick up my renewal cheque card when it arrives and then will have to go through this battle again.
