I bought 2 testing kits some 2 weeks ago and was sent 2 bottles and 2 return bags, so I put a bottle in each bag. When DPD came to pick up, they only had one label so put both my bags in a larger bag and the driver said he would re-do the labels when he got back to Swindon depot. Knowing delivery companies as I do, I was worried this might not happen but 2 weeks later I received confirmation from yourselves that the samples were ok. On the same day (this Wednesday), I received another e-mail telling me DPD would pick up samples that day. They arrived only to be told that they had a wasted journey and there were no samples to pick up. I think the admin needs tightening up at your end to stop sending duplicate e-mails and repeat instructions to DPD.
