Not Cancelling Bury Line Request

After my tech came to fix the line outside, everything is fixed. The house already has a buried line. The technician said he just had to reconnect it. Now, within the last week I'm receiving notifications of it being marked and bury line request. I've called, sat on the phone for 30 mins and was told it was cancelled and told by three chat agents it's cancelled. Now there's lines and flags in my yard! This needs to be fixed now before they even attempt to dig.
