Selvedge magazine subscription

I had a bit of a shock when I checked my bank account to see that £25.00 had been taken out by Selvedge magazine, when I only set it up in may and have had 2 issues so far. When checking the T&C s, they automatically renew after the 3rd issue has been dispatched. As I had my last issue in June, I wasn’t expecting the next until end of August at the earliest so was not happy to see money taken in July. I wondered if anyone else had same experience? I will be contacting them today as I had no intention of continuing subscritption at £25
