First of all, my boss is very good and comprehensive person. I work on a Software Development company, and, currently, all our services are running on AWS system. But, the proxies that we need couldn't run on Amazon service. So my boss asked for me to use the free trials on other Cloud Services Company and when I had find it the functional platform for us I should sent to him the pricing. After some search I figure out that our proxies could run on Google Cloud and Azure systems.
As you probably know, to use the free trial counts, you must insert your credit card. So a inserted my, obviously, because I want just to test. After I tell my boss that we have our proxies running in those systems, I sent to him the prices of each instance. But as we are tied to dates I said to him that we could resolve the price and count later and that we should give attentions to other tasks that were more important. He agreed with me. The problem is that the time of free trial expired on Google Cloud and now I have been charged in $9,00 (which in Brazil is a considerable value). How can I ask for him to pay this value without been greed or something like that?
