I purchased a phone from carphone warehouse a week and a half ago, my billing says I’ve used 80% of my mobile data, but with this covid19, I’ve barely been out of the house, how can this be possible?

Make sure you turn off data. If your WiFi drops out, your phone will start using data instead. This only has to happen at the wrong time to start mincing though your data allowance.
Also turn off options to dual connect (i.e. there is an option on newer phones to connect to wifi AND data when the WiFi is slow).
If both of these are okay, I would check your actual ID account to see the real data usage. I would not trust a phone to give you information which only your network should have. Hopefully there will be a mismatch.
If this matches, then you need to do some investagative work. Look through your phone to see when and what data was used on and see if you can find the problem. Unfortunately this task will be down to you and nothing to do with the network. More of a personal protective measure.
