Terrible staff!

Struggling Every month to get my sons diabetic medication. Staff dont call back as promised. The staff needs serious training in customer care. Yesterday i was told that there is NO Sensors in the country! After talking to the medtronic rep, i was advised that it is not true and that Medipost should just order stock. Imagine telling a diabetic patient that there is no sensors, and it is not not true! I dredd placing my order every month. I wish i could buy from someone else. Really bad Medipost
