Telkom 10th Birthday of Lies

In Number I've received message from Telkom 10th Birthday saying I qualify to enter a competition with a unique code I then click Internet instead of dealing the number I was given I then went on Internet and it says to redeem my voucher I've to enter phone numbers, names and unique code with I enter this was 03 December around 16:05 which I did entered, and it says I've won a weekend away and I screen shot just for incase, I waited for an sms voucher which I didn't get even today, I then went again on the website to look for TLC Marketing Numbers *** I then left a message and later on dealed the number which they don't answer I tried day after day, it just says leave invoice, email and numbers so they will get back to me, they didnt get back to me, I think Telkom is becoming ******* and Public need to know about their Lies, it's a big company of ****, I still wanna expose them to media as I'm very upset with their lies
