PLEASE REMOVE ME FROM YOUR MARKETING LIST

Cell-C keeps spamming me. I've emailed and called multiple times for them to remove me from their SMS list but they just don't seem to care.

Their opt-out system doesn't work and I'm receiving SMS's from them every other day even though I'm not even a customer.

I've contacted their customer care on 9 separate occasions and I keep getting told the issue will be resolved only to receive SMS's from them again a few days later.
