I'm not familiar with that flavor myself and whether it should have a coconut like flavor. I suppose it's possible something could get messed up on their end, but it's certainly not common. You might try contacting their customer service to ping them about it. I've found their flavor descriptions fairly accurate, myself.
You might also try steeping the
juice to see if it improves. Take the cap off, put it in a dark place and leave it there for a day or two. Then, recap and shake the bottle 2-3x a day, if possible for another few days. Let it sit for a week and try again. If it's still not tasty, try again in another week. Of course, this won't make a coconut taste like a kiwi...but it may improve the flavor for you.
As far as other choices, there's many. Ahlusion, Alien Vision, Nicoticket, Alice in Vapeland, Heather's Heavenly Vapes...many others, too. I wouldn't totally give up on MBV, though, maybe try something else from them. They're great when you find a "hit" for you because it's fairly inexpensive compared to elsewhere.
