The problem with the Glenlivet?? could be one of two reasons, firstly it could be "corky", smell the cork and see if that's the problem. If it is then I would suggest you contact the store you bought it from and complain. They should offer to either replace or to contact the shippers to get a replacement.
The second problem if it's quite sharp and bitter is that it's been in contact with either heat or sunlight for too long and thats a problem for the shop where you bought it.
Hope this helps
ps it could also be their belnder/malt master having a bad day
