UberPass service

I have an account with Uber which is a great service to use. But, for the past 3/4 months, an amount of R100 is deducted from my account and it happens around the 12th -16th of every month. I have tried to call Uber, contacted their "help" menu, which never seems to be working or assisting, and I have called my bank several times and they said I have to contact Uber. Now, Uber, can you kindly unsubscribe me to your service of R100 per month, "UberPass" which I never subscribed to and to which I use your services rarely. I will not subscribe to a service that will not benefit me. It has been over 3 months now, and I have honestly tried to stop this service and unfortunately, I am not getting assited.

Thank you
