Theft at Viva Rosebank & bad customer service

Last week Tuesday my locker was broken into, even with a lock on it. My 2 cellphones (an iPhone 6 & an iPhone 8) along with R1700 in cash was ****** out of my handbag. Viva Gym Rosebank has been so unsupportive in this regard, I was told that they would conduct an investigation & I would receive a call from the manager with feedback. It has been a full week now & still no feedback has been given, even after I followed up with them thrice in the last week. I’m so disappointed in how they have handled, or rather their inability to handle, my case. I would’ve appreciated at least some sort of feedback or reassurance. I have been inundated with additional costs regarding the insurance of my phone as the one was not insured & since R1700 had been taken from my bag. When I enquired about it this morning I was simply told that because there is no footage in the lockers there was nothing they could do. The gentleman I spoke to also advised me that as of yesterday they no longer have a manager. This was certainly not the first case of theft I have heard of taking place at the Viva gym in Rosebank, even the police officers at the Rosebank police station were aware of the increase in theft cases. Yet in the last two years that I have been a member they have done nothing regarding their security & have no contingencies in place in cases like these. I am now forced to cancel my membership & pay extra costs to join another gym as I cannot gym in peace having to worry that my belongings are safe.
