I'm terribly disappointed that I can't trust this service to charge me correctly, and their customer service is clueless and appalling. I was overcharged AFTER my delivery for amounts that they refuse to explain. When I called everyone I spoke to was unable to answer any simple and direct questions about the billing without putting me on hold to consult with someone else, and still could not answer directly. I gave up and tried email.
I had to send 8 emails exchanged with two different agents before someone grudgingly agreed to refund me an amount less than I was overcharged. I will consider myself lucky I'm getting anything back. It's too bad, my order was exactly what I asked for my shopper/driver could not have been nicer.
I won't use this service again.
