Cancel my F-LTE subscription for ***

I have phoned and phoned and held on for 20+ minutes or so at a time with nobody answering the call except the repetitive 'Superstars', more like Disas-stars, and 'your call is important to us' messages to speak to somebody to cancel my subscription. I have decided that 200GB per month is too little, instead I need uncapped LTE, and due to your fantastically 'non existant' service I have opted to cancel with the permitted 5 day period. Strangely emails come back as 'unattended mailbox' and calls unanswered even whatsapp group has no cancel option. I understand that it is lockdown and most call centres worked from home at level 4 but we are at level 3 now and telecommunications are permitted to work, but no, 'high call volumes', is easier to play via a recording. How can you just ignore your customers, pathetic Supersonic pathetic! Please arrange to fetch the router and sim card and cancel my debit order asap.
