After many years putting up with Cell C I'm done!

I have been a premier customer of Cell C for 10 years. I have had 4 to 5 accounts with them in my personal capacity, payment is made automatically on the 30th of each month off my Credit Card. In February they sent me an SMS saying my international roaming has been cancelled and I should call the call center to activate if needed. I travel frequently but given restrictions now have not. I am about to go on an international trip and called in to active the roaming. They gave me a proper running around telling me there are arrears (there are not) and then placed me on hold for 25 minutes. Still not resolved. Moving to another service provider when I get back.
