Coffee steri stumpie that smelt worse than 10 dead rats!!!!!!!

I bought a coffee flavoured steri stumpie on a Saturday afternoon from Checkers Watefall. R18.99.... When I opened it on Sunday morning, the smell was vile, putrid, sickening, it was worse then off. the whole house stank of this vile liquid, I happened to get some on my hands when I threw the liquid away, and nothing would get rid of the stench off my hands.....I wanted to vomit, my family wanted to vomit. I got in my car with the bottle, wrapped in 3 checkers packets, took it back the Checkers, the customers and staff near the Manager desk could smell it when unwrapped. The manager asked a staff member to take it outside to discard it, even they felt ill and could not get the smell of their hands. They refunded me R18.99, the Manager said he would deal with it on Monday and get back to me ( of course he did not get back to me) he even took the batch number down........... and I get an apology letter for all that I went through. This service is below standard, and is just totally unacceptable and unprofessional..... for all the time and money wasted on something that smelt worse than 10 dead rats !!!!!!
