This particular Big O, is run by a number of scammers.  I took my car to get a transmission flush done.  They left my transmission overfilled by a quart.  I had to take it back and it was still overfilled when I left.  I bought a card from a solicitor from this company which included a number of free services.  I asked the seller if I would be able to provide my own oil (syn) and filter and all they would need to do is the labor.  The seller said that would be fine.  So I bought the card and a week later I go to store to get service done.  \n\nAs soon as I mentioned that I had that 'discount' card, the guy behind the counter is like \"well let's go outside and take a look at the car\".  We go outside and he says that one of my tires needs to be changed.  He says that he doesn't even feel safe driving it into the shop (the tire had some cracks, but the tread was perfectly fine, no balding or uneven wear.  It was fine).  So I agree and we go inside and he gives me a quote.  He tells me that they only have on tire in stock and it's $128.  It's a Dodge stratus with standard tires and stock rims.  I ask him why it's so expensive and he says that it's because the speed rating is an S and that all the tires need to keep the same speed rating.  I did not realize it at the time but I bought two other tires for the car from this same Big O and they were $87.  So I decide that I'm going to take the car somewhere else to get the tire.  \n\nI took it to discount tire and got a tire for $88. Took it back to the Big O tire to get the service I had originally taken it in for (oil change and tire balance).  The same guy tells me that it's the company's policy that they must use their own oil and filter.  So I told them that's fine and I ask them to do the tire balance.  He tells me that even though I have a card for one FREE tire balance that they are still going to charge me $3 per weight used because they need to use aluminum weights since my rims are aluminum alloy.  The rims had lead weights on them already.  I've never even heard of aluminum weights being used to balance a tire.  So I figured at that point that the person was lying to me and just wanted to take my money and probably wouldn't have even done the service anyways.  \n\nI immediately took my dodge to the Big O on Rock Springs.  Huge difference in service.  I was greeted immediately when I arrived.  I told him that I wanted to do tire balance and that I had a card for a Free Tire balance.  They took the coupon, offered a few other services which I turned down and they proceeded to do the tire balance....  FOR FREE.  \n\nI called Corporate to notify them of the disparity of the two stores.  I don't think they cared much.  They asked what I wanted them to do and all I asked for was a refund for the card I bought, to which the agreed.  Frankly I don't trust any repair shop too much, but this repair shop I believe is short changing it's customers if not steeling.  I don't blame Big O as a corporation, but this one at Centennial is one to avoid.
