Panic button Disgrace

After a year, all 3 panic buttons stop working. Upon enquiring, Secura tells me, it's the batteries (coincidence; all 3 at once?), and I can't just replace them with any battery, it needs to ne THEIR battery. But no, they don't have; it's on order. So after a month (of not being able to use the panic buttons, of either 3 of us jaf an emergency, despite having paid R1000 per panic button), I ask the question. The answer, no, the batteries have not arrived. After two months, then 3 months, the answer is blunt: 'No, sorry'. So I escaled the issue and Vuala! They have batteries, but are you sitting down?...at R150 + VAT EACH! So I bought 3, out of desperation. This was 9 days ago; the one started working, after much back-and-forth and a 'technical issue' on their side was fixed, but still, no luck with the other two. I'm hoping their Ops is more organized, because, eish, if/when I have a crisis one day, please don't let it be the customer relations/ technical team thar answwrs my call!
