No contact- under warranty

So i brought 3 vapes at vape king. They do not even put the points on your account. The 2nd last vape just stoped working within the 3 month warranty. I took the vape in last week saturday as the vape shop is close when i am done with work and the guy said that he will let me know in the week what will happen as the vape is only working when on charge. After the week with no contact i went back Saterday to find out what is happening. The guy said that it was sent to head office but he will see if the guy that was suppose to take it did took it and if not he will give a new vape (My vape is not in stock). I stoped smoking and uses my vape to not smoke cigarettes. Now i have to smoke cigarettes again as it is going for the 2nd week how long do you wait for feedback to know if it is going to be fixed or get a new on. If it takes almost 2 weeks to know what is going on, how long will it take to fix the vape???
