Load Shedding Back-up plan

I would like to complain about Virgin Active Rooihuiskraal (situated at ********** It is very unfair to us customers, that when there is load shedding there is no back-up for electrical equipment's to be functional, so that members can continue training. As paying customers, we deserve the service that we pay for, now i am wondering since load shedding is here to stay, do we have to exercise according to schedule of load shedding? while they (Virgin Active) debit our accounts monthly without reducing any costs? It will be best if Virgin Active make a back up for us customers as this IS NOT FAIR AT ALL.
