I signed up @99p but never got round to using this because my business never launched. I wasn’t given notification & I’ve then been charged £14.99 :( Could I get refunded

I thought I’d make use of it. 99p a month seemed ok to keep it going but after not being able to make use of it, I wasn’t alerted the price would go up. And suddenly I see the £14.99 charge. It would be nice if it could be refunded as it’s really money down the drain for me and stings even more with tax return coming up!
