How can I f*ck with UberEats ?

I have got a bit of time on my hand and wanna mess with them. I signed up for one month of free UberOne and then 4.99 each month. I have a screen grab showing Apple Pay 0.00 GBP. But as soon as the transaction went through my account was deducted with 0.60 GBP. I know it's not a big amount but the delivery company are messing with us in all ways possible. If you have some random suggestions what I should do that will make them think let me know
