3/2/2018 was my estimated refund date. I had a TurboTax prepaid card sent the house. I have a $0 amount. I was supposed to have 348. IRS site not showing anything.

IRS tracking site not working for me. I've called several numbers, all with roadblocks. 2/04/2018 I filed.  2/9/2018 my refunds were accepted. 3/2/2018 was my estimated refund date. $0 balance on my prepaid card. Nobody can give me an honest answer. 

WHERE IS MY REFUND MONEY ?
