Do they handle payment? When I lived in Belgium there were a few services like what you describe (2000-2001 ish), but they were all basically glorified Yellow Pages - they'd find and call a service provider for you, but from there on out you were on your own. Also don't bother sending them a list like '6 eggs, a gallon of milk and a pair of black socks', which it seems this service does cater for.
No you can't make purchases through them, and you can't store information with them.
The only type of payment involved is the service fee when you call the number. Other than that they look up information for you, or answer questions for you. Like a google phone operator.
