Where’s my refund or upgrade?

I emailed sweet nitro 2-3 days ago because I was charged 5 bucks for the championship upgrade and never got it. No response, upgrade that I purchased or refund. Horrible customer support.
Thats why this game loses players. It's gone to shit really quick.
Tell your bank you want a refund...or Paypal if you used them.
Same thing happened to me. Support would not refund me or give me upgrades I paid for. Extremely slow response and they would not refund me. I’m reporting them to those with authority. What a rip-off game.
