Returns - shocking service

Hi all, I really hate to do this, but please be aware that the returns policy is not all that it is cracked up to be ... I returned a faulty watch on the 28th of March ... still haven't received the replacement ... almost a month later! I e-mail their customer service desk at least twice a week and the response I get every time is

Thank you for your response.

We are following up with the supplier and will revert as soon as feedback is provided.

Enjoy the rest of your day.

And I never get any feedback!
