Red Premium uprade - NO PROMO CODE!!!!

Vodacom has a promo running that if you upgrade to one of the RED plans you will receive a free rugby jersey. I upgraded to the RED PREMIUM plan, did not receive the promo code and when I contacted them they first said that promo is over, but yet is advertised on their site to be running till 18 JULY 2018. The agent then spoke to her supervisor her who corrected her and informed me that I did qualify for the promo and that I will receive the code via sms. She gave me a email address ********** and said to email them. Which I did, only to be referred by them to ********** all mails to this address has failed. No sms received, no help via the email. So please don't ask people to rate your services because its a joke! Today I will spend another two hours on the phone to be given the run around, that is what makes me so disgusted with Vodacom service... non-existent service
