When purchasing virtual cash in an online game try to do it during business hours and read the official forums in regards to errors prior to purchasing anything.

I’ve purchased some last night for a game called Zombie Lane on Google+ last night and due to an in game error this virtual cash disappeared.

Unfortunately for me I did not read the forum posts regarding this known error. I usually do but didn’t this time. And now I’ve got to wait until Monday to get a response.
