They tend to respond on Twatter better than the phone in general. They are a waste of oxygen in our area. We had the same issue where a failed delivery becomes a farce. If you have the delivery failed ticket then just pitch up at their depot and be polite but forceful. Whilst you are there get the seller to start a call with them and explain you are at the depot trying to collect it at the same time.

Everyone loves a Morgan. Even me, unless it's broken again.
