When will the theft stop at virgin active kenilwor

I am a really disgusted in the lack of security at virgin active.. I was a previous member of virgin active 2 years ago but cancelled my contract because of theft, they had broken into my locker and ****** my cellphone, until today I have not heard any follow up from the gym...besides that I decided 5 days ago I would give the gym another chance because of convenience of where they are situated, so I opened up a new contract on the 16 July 2015, 5 days after opening up a new membership the same thing happened , today I went for a training session, locked my goods up and went for the session, upon returning to the changing rooms I came to find that my locker had been opened and lock removed the door was even open, I checked my bag immediately my wallet had been ******, R1000 cash money license cards everything gone! When I notify the staff I had to fill in form, this is the second time this happens is virgin active not going to do anything about this theft ?am I not going to be compensated for this inconvenience ? All they said is they'll get back to me as they will look further into this...yeah right ,let's see, I am still waiting to hear about the first theft 2 years ago,
