No refund for system problems

Sadly, they would not give me a refund for the month although the payment had not come out of my account yet (still pending). I only paid for premium to listen on my mobile device in the car. I cancelled premium and emailed about a refund because it would not play off of my mobile device and gave me the message: your license to listen offline has now expired, please go online to renew it. For two months the ten dollars was drafted out of my account, yet no music would play on my mobile device. How disappointing! Customer service can really use improvement. I at least deserve a partial refund since it is only 8 days into the month of July.
