Faults in a product

I bought a bottle of wine in March, only to realise it had an unfami**** object at the bottom of the bottle. I escalated it with Checkers via Facebook inbox. I was asked to return the bottle to the store and I did. I was then told the store manager will send this to the supplier to do some tests and I should await feedback. I have been sick and having some abnormalities ever since. I followed up on this since I still have not received feedback a month later, I was then told the manager misplaced the bottle and the store stuff took it as part of the trash and threw it away.
