I ordered a therm 470ml by mistake. Immediately after the purchase, I contacted customer service to inform them and cancel the purchase. He told me to wait for the delivery to arrive and reject the package, then it would cancel straight away. I did exactly like that, but the delivery guy from DPD said that that wasn't the right procedure and that the company was aware of that. They have to call DPD to cancel it. I contacted customer service again, and now they told me that there is no refund. I have open a case on Paypal. I have the item unopened with me waiting for the collection. I won't pay any cancelation or collection. Very dissappointed with the service.
