How to cancel an order?

Mods, I sent an email to the US store and Arduino support but haven't gotten an reply back yet.
I ordered a Uno Starter Kit but decided to not purchase one yet. I am pretty sure it has not been shipped. Is there a phone number I can call?

Order #: 200037255

There is no phone number. Contacting Arduino Store support via this form is the best thing you can do:

But hey, get that starter kit. You could have a ton of fun and learn a lot from it. The Arduino Mega I bought on a whim 7 years ago certainly changed my life.

Yeah I will eventually get something just wanted to do some more research on what to get. Still no reply. Do any of the mods checks this forum?

Not too often the store people get in here.
Will push up a back channel to see if there is any response.
best we can do.
