If it were possible to give zero stars, I would. Absolutely useless. Have failed to deliver two separate parcels in the space of a week, both times claiming to have delivered. The first time, they could not provide any proof of delivery. The second time, a photo on the Yodel app was not my door. They are impossible to contact by phone. Their webchat is a series of cut-and-paste responses from India promising to escalate, but it's just a black hole. Nobody ever gets back to you.
From now on, any online company who uses Yodel will not get my business. How Yodel themselves manage to stay in business is beyond me.
