There are many modes of communication that can be used and some online chat bot is likely most unreliable. If you can't walk into the store for a talk then phone call is probably second best.Perhaps HMS communication isn't what it should be but it's time to move on. Ultimately this is all meaningless so why prolong things? What is it going to accomplish? It's not like they are a lying or cheating lover which might actually warrant such bruised feelings.
