Tevo's Purple-to-Blue Gloop a Bloop!

Tevo's Gloop: bought at Pick 'n Pay Randridge Mall: the 'Chameleon Putty' heat-activated from purple to blue - supposed to turn blue when it gets warm? It does not: it stays purple. On top of that it is very difficult to 'play' with: it is not malleable - unless maybe you are Superman...unfortunately, he was not in the tin with my Gloop! Bought the heat-activated purple-to-pink one a month ago and that one is fine-- easy to play with- quite fun, actually! Wrote Tevo an e-mail...4 days later and they still have not responded. Do they know what customer service is, or are they only interested in Sales?!
