Been told that I won competition

On the 20 of November 2015, a competition was advertised on Daily sun newspaper which I entered and received an sms that I won the competition and I must look out for a white envelope which will be posted to me. I then recieved the envelope on the 24th of January 2015 stating that I had won the competition and I need to claim my prize by sending a reply not later than 10days and place an order of the Best Product which were enclose inside the envelope on a catalogue to guarantee me the bonus of R50 000 however the order had to be for an amount of R500 or more and the prove of payment needs to be enclosed. I did all that and on the 30th I called to find out if my response was received and was advised that yes however I will be contacted regarding the price, the 09th of Feb I recieve an invitation to the prize giving and when I call to find out about this, am told that the letter is an example of what I could have received had I won the competition of which it doesn't say that it's a sample or eg It clearly states that with ur full names u have won and been invited to....I think this is just a **** for people to oder their products and it should be stopped.
