I have already sent Bullyion an email to let you know why I want to return this collar in the last few days, but I STILL haven't had a reply or any instructions on how to send it back before I order the same collar x2 sizes bigger?! As I'm in credit for returning the collar before this one but a slightly different design, I'm not reordering another one until this collar has been returned and I have been refunded?! The dog harnesses, collars, leads etc are great, design, quality, price and choice...
