Wheelchairs and elderly customers

I would like to call attention to the problem with your security doors and wheelchairs. I used to work for a branch that was ****** so I understand the safety aspect. My grandmother is in a wheelchair and cannot push herself in it, so when we arrived at the branch I asked the security guard to open the door for her so I can push her through, he sighed and opened the door, but then once she was in the little glass box she couldnt push open the door and the door didnt have a handle on the other side for someone to help her, she was stuck. This is a bit rediculous. Find a way to rectify this problem.
