Misrouting of parcels

3 Orders in a row was misrouted, with different delivery addresses, as when the first one was misrouted they advised us to change the address. Second time I phoned, as I already had another order placed which was delayed due to stock needing to come from the supplier. I was promised by the call centre agent that she will ensure it gets routed to the correct branch. Today this order has been misrouted once again. I phoned the branch, and once again I am advised to either change my delivery address or to opt for collection, but the whole order will need to be cancelled and replace for collection. Problem is the products I ordered are now not on the sale price anymore, which means I now have to pay full price for the product due to their errors. You cannot speak to anyone superior, only to the contact centre agents, and they cannot really assist with resolving the issues you are facing as a customer.
