Broken device delivered, waiting for replacement

I ordered a Bluetooth speaker on the e bucks store December 2015, the device was delivered and it was broken out of the box. <br> <br> I contacted the store and they said that the device will be exchanged for a new one, I gave them a updated address and they just never came to do the exchange. I've contacted the e bucks store numerous times regarding this with no luck. I dont even get a response with a status on what is happening. <br> <br> Initially I was impressed with how fast they delivered, but I have to say the after sales service is very bad. <br> <br>
