Home-Connect Master Corporate Bully

This is the worst form of corporate bullying ever. I need to vacate my property, but have been unable to secure my next address. However I need to give notice on my internet service. Tried to do it on both the app and desktop, no luck. Monday 3 Feb, 1st thing I email asking for either a pause on the account from 1 March or cancellation until I know where next address will be. Home connect says no, cancellation will only be effective from 1 March, so even if I do not use the service, I will pay for March. And, I will be liable for paying a penalty for not staying a customer for 12 months - although technically this isn't true, I have been a customer for more than 5 years. 5 years at one address and since April 2024 at another, but this is a breach of my contract - I'm not allowed to move house it seems. Best yet, I get a letter of demand from them this morning citing the arrears amount for Feb (the penalty amount of R2627.35) due immediately or my service will be suspended today. Note that my service fees for Feb is paid in full. How can companies be allowed to get away with this? In my correspondence with Home-Connect, I was assured, that this is the way it's going to be, and I just have to pay up.
