I work from home and don't always have time to cook or run out for food so this is immensely convenient for me, to pick up the phone and have home cooked meals from restraurants I like delivered to my door. Yes, a few times I could have complained about a driver being late or rude or what have you, but on the whole the service is invaluable to me.
So the words 'professional' and 'customer service' don't generally come to my mind when I think about websites selling virtual items, but that is what you get here. I've visited multiple times and dealt with 2 or 3 different people on their chat and have been happy with how polite and professional they were, in addition to taking the time to explain things I didn't understand about the process.
