I would humbly suggest the following. Assuming you still want the upgraded amps, inform them that unless you receive the tracking number within the next 24 hours and delivery of the upgraded unit by end of the week, you will be proceeding with a refund request from your bank.
This all depends of course on whether you still want the upgraded unit.
