How do I cancel my SaleHoo membership immediately?

Could someone please advise me on my concern below.

When ordering this service or having questions related to SaleHoo's services, I got immediate responses. Now I've chosen to cancel my membership, (have only been a member for a couple of days) and I hear from no one. Could someone please explain this to me?

Hi gbayer14,

Please take into consideration the time zone difference of our locations. But we do answer all our support emails within 24 hours of receipt from Monday to Friday.

I have just replied to your refund request, including the one you made through ClickBank.

It's unfortunate you have decided to leave us...

All the best!
