Query: Bummer

I bought this jogger and loved it at first. It has turned into a dud. It pulls to the left, the frame is creaking under the strain of having to correct it from pulling. I don't use it for jogging- just trips around the block with my 8 month old and to a local park where there's gravel. Tried to fix it but we can't get it right. Hope you have better luck. Still waiting on Baby Trend to return my call.**Update... Baby Trend never called me back but I did finally get them. The customer service rep said I could send it back but if their mechanic fixed it the problem and then dis-assembled it and sent it back I may still have a problem because I am not a mechanic and the problem might just be me. Not friendly service. I never sent it back and use it very little.
