Actually, just go to the grocery store, but a disposable credit card with just as much as you need on it, use that, throw it out. Need a phone number, get a prepaid phone while you're at it. Who's gonna accuse you for cheating on them at the Safeway??

so in the statement is it AMBD or AVD??

ADL Media Inc is the billing code for AshleyMadison.com, a website for married people wishing to have an affair.  The comany didn't call you, your spouse had to register for this service.

That company handles a lot of different online billing.  We downloaded some software and that is the company who processed the payment.

trying to figure out who called from this number

That may be true, but I am sitting here looking at the AshleyMadison.com PayPal payment page and it says,  "You will be billed under 'ADL MEDIA' by PayPal."  If you see that on a cc statement or PayPal account it definitely warrants some investigation.  More likely than not, somebody has some explaining to do.  I think I'll pass on the PayPal payment and pay with a pre-paid cc.
