If ever it's been advised that you would be contacted by the winback department, I would make sure I didn't miss a call from us and wait until we reach you.
You can always contact us on Facebook or Twitter if you need assistance.
Thanks Anthony, what should I do in this situation? Would you be able to forward my request to the winback department? BTW that email was sent from email@example.com, I tried replying to that email but still got no response.
