I purchase $10 in gas at shells in Stockton ca. At pump #7. 717 west 8th st 95206 my gas gage didn’t move at all and gage is under the empty sign. So I went in to let the cashier know that no gas was coming out. Cashier told me it’s not they’re problem. So I put another $6 at another put to show that pump wasn’t working and my gage move. And they wouldn’t refund me my $10 or put in a gas card at least. They where rude and unprofessional. I’d like to know how do I come about getting my $10 back .
