STILL EXPECTED TO PAY WHEN CONTRACT FROZEN

Good day, I froze my contract for 3 months and am told that I am still liable for 50% of the monthly fees. Apparently this is the terms and conditions. When asked to see it I was told they don't send it to customers. I have requested a copy of my contract and I am still waiting. No feedback 1 month later. They have pathetic customer service. They are forcing me to cancel
