Trouble

Because an email and the phone number of the guide are wrong, I cannot come into contact with the guide.

Let us know the guide whose email and phone number are wrong. We are going to search. If we cannot find the guide, we are going to generate new access key for you.

The guide whom I sent an email to does not reply.

There is individual difference in frequency to check an email. If you know their phone number, we suggest you call to them.
But when you cannot contact with them, let us know their name and guide number.

I input wrong email address on the payment page.

If you know the wrong email address you input, let us know this email address, your name, and the day of payment by email. If you don't know, let us know your name and the day of payment.
After checking your payment, we are going to generate new access key for you.
