False advertising, pathetic customer service, ********

I won a Lindt competition. The prize clearly stated a voucher. I didn't receive it and after complaining got it weeks later. The chocolate I received definitely were not to the value of what was advertised. I suspect a **** because the lady who delivered never asked for identification and I didn't have to sign for anything. I rechecked the competition post and on 3 Oct, weeks after winning it was edited from voucher to hamper. I actually think that ******* Lindt employees are benefitting from the vouchers. Lindt has the worst customer service for such a huge well renowned company. No responses whatsoever. Yes it was a competition but why the false advertising? If a competition is run and a prize if to a certain value, honour it.
