Not clear from your statement if you heard anything during those 100 days after placing your order. Did you pay at the time of ordering or when the item was shipped?
In any case, if you heard nothing during those 100 days despite making attempts to get a response from the seller, then "Thank you very much" would be my thought, and I would never order anything from any seller who is going to hang me high and dry for 30 days, let alone 100 days.
If the seller has some emergency, that is fine, but if not keeping in touch with a customer is his or her usual way of doing business, I will choose to have nothing to do with him or her, because it is my money. I don't care how great his or her products are.
