I specifically come on here with the same problem. With Ypsomed, it was so simple - phone up, give your name, address and hospital then they would send you 2-3 boxes out which you would just take to the post office when full. With Insulet, the call took ages, then today when the un-assembled box arrived with the various bags and instruction leaflets, I realised you then have to phone DHL up to arrange collection (there should be a paper titled 'Insulet. Return instructions for Insulet Pods and/ or PDM(EU)' and quote the account no. on the instruction sheet and the tracking no. on the shipping label . I can't figure out the best way to contact them. I have found a phone number on the DHL website 02476 937770, whether that's the right department I'm not sure . It just seems so much hassle just to return a box of pods!!!
