Very disappointed customer

I bought an calculator online and was supposed to have been delivered this past tuesday at around 6pm i went to check why i have not yet received my order to try and track it only to find my order was cancelled with no prior communication till this date and i have also not received my money back. I am very dissappointed in thier online service. I would have never thought a big store such as Game would have such poor ********* customer service and to add to that theres not even a direct customer service number to contact with this regard.
