THIS IS A **** BUY

I purchased an item from their advert on Facebook. Even paid for shipping. They now say I paid for a membership to their group. They say it’s in T&C’s when you buy. They have taken two amounts out of my account. I NEVER subscribed to any Bicycle store… I’m 57yrs old with compound spinal fractures and cannot ride a bike. They refuse to refund my money. They are ******!!! This is a ****!!!
