Apollo Pharmacy — order cancelled but no refund yet

Hi,
I ordered some stuff from apollopharmacy order #[protected], they cancelled it within a week on their end and not conveyed any message to me. When i inquired about it, they mentioned it's cancelled and you will get refund in 3-4 days. Now it's 3 week already gone, still no refund and just telling me, will look into it./... Worst service...
I want my money back...
