Bug description:
Argent Gruntling or Argent Squire are supposed to have a banner on their backs, they are supposed to offer the possibility (dialogue option) to change this banner to any of the factions the player is a champion of and are NOT supposed to offer any service except when a player buys and uses a pony bridle. Currently, these pets offer banking service by default and on demand. This isn't supposed to happen.
When a players buys and uses an Argent Pony Bridle, these pets should mount up when the player mount up and offer the possibility to use one of 3 services for 3 minutes and on a 4 hours CD : bank, vendor (no repairs) and mailbox.

It doesnt work for me too. My normal Argent Squire opens bank when I click on him but now I bought the item -Argent pony bridle, for 150 Champion's Seal (https://www.wow-freakz.com/item_finder.php?item=47541), I recived achivement but he still opens only bank. It should show a windows where I can select: Visit bank, vendor or mailbox. It should also mount up on his pony when I mount up but he doesnt
