After you file

I have tried 6 times to reach the turbo tax.dispute dept due to the several double charges on my card. I have 5 charges on my account that were charged 2 times to my card. Every time I have called them I get someone who picks up amd then transfers me to the dispute dept and from there no one ever picks up I've waited over an hour each time and once I waited just to see if they were going to pick up I waited for 2 hours amd 16 minutes and still no one answered.. I feel that they are doing this on purpose not wanting to give me my money back they total over 300. Im a single mom and this is alot of money to me.and my kids. Please help
