webmail is terrible

I am trying to clean up my emails. It is ludicrous. the guy who designed this should have his head on a pike GOT style. I take time to select emails at the end of my date list from the past. this takes a cumbersome impatient time. once I have that list in trash I try to empty my trash. nope not happening it only deletes what appears visually I assume. so chunk chunk bundle up trash but trash has to be deleted in painfully increments not acceptable. what do we pay you for? this is unacceptable from a internet service that has been around.
