Main Merchant is online

I approved a charge on my credit card by telephone for my adult son at a dentist. The dentist then charged a second separate visit for additional work without asking me for approval. I am fighting this, but my credit card company is not helping much. Do I have recourse?

I just curious to know, if not, how should I move the bed into my home? How much do I need to pay? (Bay Area)

Can anybody help with finding a merchant service provider for my new online car hire company.
I need to check/authorise a transaction before we proceed with the hire agreement but i dont need to take the money until the car is returned. If there is no damage on the car then no money would be taken from the card.
I just need to check if the funds required to cover the deposit are available on the card or not
Any help would be much appreciated

Currently, our website is a customer of authorize.net. We pay authorize.net 20 dollars a month for their gateway. They told us we also require a merchant services account in order to process credit cards via our website.
Where can I get a merchant service account or a package that includes authorize.net at the cheapest price?! We tried quite a few banks but authorize.net and the banks come to more than 45$ per month!
Thank you.

does recurring billing come as a service from the merchant account provider or the payment gateway? im a bit confused.

Not an account? What is the correct way?

I am interested in setting up this service for my auctions because it is cheaper than Paypal (although I’ll probably still offer Paypal as well) and I can sell stuff under the mature audience section, which PayPal does not allow.
Has anyone used this service for their ebay auctions?
