Motorola Defy :: Plug Doesn't Work, Unable To Get Replacement?

The plug part of my Motorola Defy stopped working so my only option at the moment is to charge via USB which isn't too great when I don't have my own computer at home at the moment so charging options are very limited.I contacted Amazon where I purchased the phone and they want me to send the whole lot back for replacement when it is just the plug part that doesn't work!i then contacted Motorola via their Chat and they were not much help either. It took them ages to respond to my query as they were busy chatting to someone else on the phone. When I eventually got a reply they said to contact CPW Accessory Repairs on 0870 087 0168. Contacted them and I was speaking to a robot and punching in different buttons on the keypad. Eventually it said to bring it in to one of the CPW stores and they may be able to help repair or replace it.What an absolute farce. It's absurd and impractical that Amazon have to replace the whole thing instead of just the small part that is faulty. It is just the plug part that doesn't work and I can't be sending the whole thing back with all my applications and viewranger maps to have to reinstall it all over again.
