Unable to receive Reset password email

[Maggi818]

I can''t log into prestashop website with the current username and password, then I tried to reset password through lost password icon, but not able to receive email back from your end.

As the reset password only available after 360 minutes,  it took too long, it is quite urgent, because I have to update information on the website. 

Please assist me with this issue. 

Thanks

Maggie
