Cell c contract ****ming

I have a problem with cellc contract, They want me to pay R720 for 30 gig everymonth. I usually pay R250 for 30 gig and In December 2022 I lost my Job and they started charging me R720 without an agreement or my concern. I did tell them to stop I did not sign up for that they continued ****ming me and today they Disconnected my line right when I have a telephone interview and I missed it whats really wrong with Cellc?? Are they going broke and now taking chances on their customers coz I have been a loyal customer for 6 years plus I never had this kind of situation instead of thanking me they make me pay 3 times as if am paying a super phone with data's and minutes. I'm not ****ed am hurt I have my own problems and you will never see me prey on other people like your doing.. Whoever is doing all this nonsense ****ming must grow up work hard and cut your cost and stop throwing robbing customers even unlimited data doesn't cost R720 it's around R500 so whats your 30 gig special about? It doesn't even last fix your bankruptcy issues and change my number to prepaid I'll get a contract somewhere else safer for my bank account. Ill pay your R250 for 5months
