Disappointing service

I lost my card inside the gym on Monday(06.11.2017) morning and immediately reported in front that I have lost my card when I was leaving the gym as I used it to swipe in and I would like it to be flagged or something needs to be done because in the morning there is fewer people so someone should have reported the card already. I was advised that there is nothing that they can do until I purchase a new card and then the older card will be revoked. I was very shocked that it is OK to promote a sale of a new card but nothing is done to assist me or protect me plus the ********** are being promoted because the person who picked up the card will enjoy a full access to the gym for something that they did not pay for until I decide to purchase a new card. I went in again today and asked for a new card as I had the R100, again the problem was made worse where I was advised that there are no cards in stock. I called requested to speak to a manager and was advised that the manager is in a meeting, my full details taken ( past 10). Still no call back received while the ********* who picked up my card is still enjoying what I am paying for as they used it on Monday( 06.11.2017) past 10 while I was at work because my shift started @9 on the day. How do you continue in a place with such service where you have no trust, not protected, where you are just being told that " it is your responsibility to purchase a new card if you have lost the older one". All I heard throughout the journey is purchase a new card than protecting my belonging ( flagging it or stopping the card from working). I'm highly disappointing with the lack of customer service received including people s****s, there is just no sense of urgency.
