DISSAPOINTED

I bought a samsung active 2 on 29 Feb from Loot. on the 8th I left a msgs saying I think its faulty. I did a reset and still the battery drained super fast. 60% just overnight everything turned off. The courier was here on the 25th to pick it up. The person on fb told me they will refund me as soon as they get the watch back. It's now 13 march and I dont get any feedback I have to constantly ask them and call them and no one is coming back to me. all I here is it's in for testing. no one can tell me for how long nothing. I even told them to send me a new one. I left msgs after msgs. How is this service acceptable? VERY DISAPPOINTED
