Worse customer service ever!!! Just gym Centurion

Do yourself a favour and don't join just gym!! They have the worse customer service ever!! I have been diligently paying my fee but now that I do not have a tag they block me from accessing the gym. I explained my situation that I will only get my tag back in a months time since I forgot it in another province and they allow me to pay the monthly membership and yet they know they will not allow me to get in! Worse part is that on 26 December 2020 my phone was stolen inside their lockers in their premises!! My question is where were their rules when they allowed a criminal to enter with another person's identity and still my phone! I am a valid member and not a criminal I should be allowed to enter the gym.
