H&R Block complaint: They have my federal return

Since March 2 I have been trying to locate my refund. Which HR BLOCK was to send to my bank account. They did send it but the bank rejected the money. So HR BLOCK sent me a check and it was returned back to HR BLOCK. (Idk why). I called multiple times (70) And couldn’t find it. Then I was told to contact the back office and have them email me a direct deposit form. Which I filled out and faxed back. They said they couldn’t read it . So I filled it out and resent. (7) times there was something wrong. The whole time I was calling and calling just to find that there was always a problem. Now I find out they RESENT the refund back to my mailing address.(supposedly)
To be honest. I don’t know where my refund is. Because I have been lied to multiple times by this financial department. Somebody please help me get my federal return refund .
