Dick's Sporting Goods review: Bicycle - gears not functioning properly

On May 22, 2020, I drove 2.5 hours to Union Gap, WA to pick up a bicycle I had ordered online since there were none to be found closer to me. I got it home and when I had a chance to ride it found out the gears were not working as they should. The were not shifting properly and the gear on the handle would show it was in 5th gear when it was in 6th. I did a "chat" today, June 2, 2020, with Dick's and the person told me to let the Union Gap store know and that I could bring it to a local store to have it serviced. Called Union Gap. Yes, they told me to call local store. Called Tukwila WA store and they said no service or adjustments could be made but I could return it, but no receipt would be given at the time. That did not sound good to me as what proof would I have that I dropped it off. Called Renton store at The Landing. They told me no, could not return — returns only after 24 hours — nothing I could do. So disappointed in this company.
