Prepaid Issues

Their pre paid system has been down for days,can't top up my account. Not by phone, not online. I reached out through FB they said will run credit card on file, it declined because it needed to be updated.I update card and then told they can't run it. I verified who I was with the first card.I now have no phone to use. I have been a customer almost 25 years and I am ready to walk away. Being told you can't do something that was just done is unacceptable
