Petro:Lube Didn't stand by Warranty Work McCalla, Alabama

I sent a truck into Petro:Lube in McCalla, Al. to have the alternator replaced on 8/05/09. On 1/22/10 alternator went out again in Oklahoma. I called Petro and spoke with service manager Nicole Ogden she said if you'll send the alternator back we will re-imburse for the alternator, but we can't do anything about the labor. I said I understood about the labor but at least the refund on the part will help. I sent back and paid frt. to return. I called Nicole about 2 months later and she said yes she got the alternator and sent in for refund, but she couldn't send check untill she was refunded. I said I wish she would have told me that from the beginning. I called back about 3 months later and she said the alternator tested good and I said no it was bad therefore it was replaced. She said it was out of her hands. She said I told you if it checked out good they wouldn't do anything about it. I said no you didn't you said send back for refund. Nicole at this point the same as told me I was a liar. I told her Petro needed to stand behind their work. She said the matter was closed. I said no if the alternator is good I want it back, that I have several trucks it will fit. Nicole said "YOU WANT IT BACK?" I said yes at least we can use it on another truck and at least re-coup a little money. She said send me the paperwork and I will send you a check. I said if she would have done that to begin with, we wouldn't be having this conversation. She said if you say another word I won't send you a check. She was very mad and very rude. She certainly did not act like that when we pulled truck in. I am still waiting as of 9/13/10.
