Placed order for delivery on Friday (when i'm home) to receive a text message from O2 (on behalf of DPD) informing me that i had changed to delivery slot to Monday - news to me as i had not contacted or spoken with anyone to arrange this; (not sure why i would be home all day on Friday and then think actually i'll rearrange for a day that i'm not home?!?). DPD FALSLY CLAIMED I HAD ASKED TO REARRANGE DELIVERY WHEN THIS DID NOT OCCUR. I spoke to O2 to find out whats going on who eventually got through to DPD (32minutes on phone with O2). O2 transfer my call i say hello; the woman at the other end says hello and then cuts off the call. I spend 10-15 minutes looking for the DPD number and then a further 42 minutes in a queue on the phone to DPD to go unanswered and eventually get fed up and hang up. I spent the time wisely and emailed the head of complaints - i've heard from them but no further communication since. I've also raised my complaint with O2 as its possible they charge the company using their service for delivery twice when the consumer allegedly changes the delivery.
