Very annoyed customer

Since the 16th of February 2022 I've been trying to cancel my contract as my 2 year period was over. I could not get through to any operator for assistance. I was retrenched and cannot afford to pay the monthly payments anymore. Today I finally get through to an operator just to ask me tons of questions why I need to cancel my contract, then her system is not working due to loadshedding. I asked her to transfer me to someone else just for the next operator to tell me I need to give notice of 20 days. Last year when I cancelled my first contract with them they did it immediately. Today their procedures have changed so whats going to happen when they debit me and there's no funds to pay? It'll be my fault. So well done and thank you for the bad service once again Mtn. The telephone staff really need to start answering their phones and stop changing procedures as they see fit.
