Well RH executed the higher call automatically without mu consent or knowledge. I tried to cover shit myself by selling the calls in an attempt to buy the stock I was short with cash from sale plus collateral, which was more than enough, but RH told me I'd have to deposit 400k+ to buy the stock.

The call gave you the right to buy the stock but you sold the call and lost the right.  You should have either executed it, left it be for your broker to figure it out, or bought the stock + sold the 65C in one transaction. 
  
 Why don't you show people your current positions and they'll tell you how to close those properly.
