Stamps.com have a free trial sign-up on their website, after which they automatically charge you 18 dollars a month.

Stamps.com makes it VERY difficult to unsubscribe from their service.

This is a scam. They want me to give up on the process so they can take my money.

The company has no unsubscribe method online. Instead, they send you to one phone number, which reroutes you to another number, which takes you to "customer service".

I've been on the line for more than 15 minutes so far without getting to talk to a representative. There is no other way to contact them to request an unsubscribe.
