Tim Hortons review: staff forgot items

I had just gone thru drivethru after being assulted erlier insodent somewhere else we ordered two 50 packs of timbits and around 8 coffees, now after a long day we got all 8 coffees no problem but we drove away before we grabbed the timbits. Now the final bill was 58$ and we paid cash. How do we resolve this issure I called and they wont give me my timbits
