Meghan Markle's sister took to social media again for another round of rant against the royal.

"I am not candy coating anything anymore! The DUCHASS should be humane to our father who has given her everything,.. and this media crap can stop! He was the one who was always there for her. Fake waves and smiles can stop. The duchASS can bow to the daddy," Samantha wrote on Twitter.

"Sorry folks there is no valid or a good argument in favor of inhumane treatment of both sides of the family and a best friend of 30 years. Snobbery and arrogance are not humanitarian traits. She has an obligation especially to treat our father with kindness," she wrote in another post while sharing Piers Morgan slamming Markle for disowning her dad.

Samantha has been attacking Markle lately for not contacting their dad following Thomas Markle Sr.'s paid interviews. However, no matter what they do, the palace has kept their silence. The Duke and Duchess of Sussex have not addressed the issue either.

"Leave her alone, she is grown she doesn't 'have' to do anything!" Emmanuella Valeris commented.

Another follower wished Samantha "peace" so she can let go of the issue and move on. However, Markle's half-sister was irked and lashed back at the user.

"I know you probably call your father collateral damage too. Did he do everything for you pay $250,000 for your college and spoil you always as well as spend his time building your drama class stages, always being there more than your mom? I bet you would dump your dad too," Samantha replied.

"It was your Dad's responsibility to take care of Meghan including educating her. As a parent you do that expecting no pay. It is a responsibility not a favor," another user replied.

Samantha has also attacked Prince Harry in the past. She even called the prince coward while insisting that Princess Diana would be ashamed of him. "Harry is a 'wuss' to allow the Duchess of Nonsense to mistreat everyone who has been close to her, especially her family. Diana would be ashamed. Stop wearing Meg's skivvies and bra and take your pants off of her!" Samantha wrote on Twitter.
