Lockdown and call barring

I am in the tourism industry, been off from work since March, haven't received a salary, but paid my account up until end May, June/July i spoke to Cell C explained the situation, I emailed them the letter we received from work explaining we will probably only return 2021, Cell C did not respond to any emails, barred my phones, and barred my wife's phone, they STOLE the 50GB her work loaded onto her phone so that she can work from home, I phoned them and told them I want that 50GB they took from her work, I do not even want their contract, they are small fries, have been with Vodacom and MTN all my life will rather go back to using them
