Shell, Tampa FL

This was the only station where I would fill up my bike. Because going to work it has a Dunkin Donuts Coffee, a 7/11 and is well lit up. Going home there is a turn arrow to cross Dale Mabry.
Until. I purchased gas in October and it started running like I put cheap gas in it. I only fill up with the 93 octane. My bike was spitting and sputtering. I tried to run the tank through and it continued to run worse, the less fuel I had in my tank.
I finally called Harley and I had the bike towed to the dealership. The dealership stated on the receipt when I picked up my bike that the issue was "Bad Gas" $306 repair bill.
There was no way someone could have added anything to my tank. I ride a retired Police bike and it has a locking fuel cap.
After I picked up my bike and got it home, I tried to call the station, only to find out the phone number listed had been disconnected. So I went down to the station in person with all my receipts, including what I paid for my fuel. I asked for the manager and was told they were not there. I left my number with the attendant and asked to have management call me. Well that never happened.
So much for being a loyal customer. $321.31 later tank drained, new spark plugs and a tank of gas. This is how I'm treated?
I have now gone to communicating with corporate. I have a case # and I am now waiting for a response.
As a long time customer, I feel very disappointed how this matter is being treated.

UPDATE: my claim was denied. Disappointed, will never use this station again. Maybe just the Dunkin Coffee
This letter is in response to your recent experience at a Shell branded station where you allege you received contaminated fuel.   This is a station supplied with motor fuel by an independent wholesale distributor, rather than by Shell directly.

I never had problems there visiting in the morning or evening. There have only been a couple times that I had to go into the store for a receipt. You do see some characters hanging around but they have never bothered me.

I like going to this gas station because it's convenient. They have a DD in the store, along a major road, and not packed during rush hour. Also if you use gas apps, they usually appear with some amount of extra discount or cash back.

Horrible customer service. I did not get a receipt from the outside, with my car wash code, and the lady inside said I needed to get in line (behind 8 others). I had paid.they were all waiting to pay for something. She could have just given me my receipt with code, which took 3 seconds.
