The battery arrived very quickly after I ordered it. unfortunately it was not the one I ordered. I e-mail them but did not receive a reply nor even an acknowledgement that it have been received. At this time I was prepared to return the battery for a replacement correct one. There website says that the will respond within two days. They did not. I sent a second e mail and was then in the process of preparing a claim in the small claims court when Uk mobile finally responded. UK mobile willingly provided a return address and a prepaid label to attach to the parcel. As soon as they received the battery, UK mobile refunded me the cost of the battery. If UK mobile had responded promptly to my first or even my second e-mail, I would have been quite happy to receive a replacement battery. They failed there own terms and conditions and caused me to be distrustful of their future actions.
