Discovery claims not sending reference number through gmail

Hi This is for the Discovery Claims department. I have sent through 2 emails from my gmail account and never received a reference number. Its now 10 days and I still haven't received my payment back. I had to eventually send it from my work email to get a reference number. Your call centre staff are also quiet rude and not willing to assist. I now need to wait another 3 days for my claim to be paid.
