Wow you really dislike their service.
I can see the point you are coming from with using it for business purposes but what also stood out was your customer service comment:
yet they are incapable of providing basic customer service…
Something that Google still havent grasped, well unless your spending thousands on Adwords then you might get landed with a good rep.
Customer service is always the top 5 things I look at when it comes to service and is one of the main reasons why I want to test something other than Paypal. I dont have an issue with using Paypal but their support is another story.
Maybe I'll think twice in online banking with Google if their customer service remains the same, either non-existent or their support contradicting one another.
