Poisoned by Groupon deals twice

Went to Kawayi restaurant in sandton - the woman who made the sushi was was also answering the phone and taking cash money for takeaways and then resumed making sushi without washing her hands - when I saw this I stopped eating my boyfriend Mark did not - needless to say we both got sick. The restaurant violated health regulations whilst making our food. <br> A WEEKS later we used a groupon to go to Santis Restaurant in Sunninghill -Mark had the Eizbein and I had the lamb cutlets - my boyfriend spent the entire next day in the toilet with a runny tummy.<br> This is two out of three restaurants that we ve been too. I phoned group on today and they said that they could not refund the deals as we had redeemed the vouchers - I said that we didn't sign up for getting food poisoned therefore the products were defective. They suggested I communicate with their vendors to resolve the issues - I said that under no circumstances would I give those restaurants the opportunity to POISON me again and that I would be reporting the issue to the health department. In what world is it okay to be POISONED a and then be CHARGED for being POISONED. <br>
