30/50G contract loaded as a 30/30G contract-losing 20G per month since Dec'17 yet paying full price for contract

Ref - social media and email posts/content:

CEO SHAMMEL JOOSUB: It is 01/03 and my contract is still reflecting 30/30 instead of the purchase 30/50. THIS IS THEFT AND ******* WITH NO REGARD FOR ME AS A SMALL BUSINESS AND RESEARCH STUDENT! I was assured this matter would be resolved by 1 March. I was patient and waited. But you still being dishonest. YOU ARE *****ING BACK 20G PER MONTH SINCE MY PURCHASE ON 30/11/17! WHY? What do you do with the ****** data? Original post in Feb 2018! - @SHAMMEL JOOSUB (CEO VODACOM) - I purchased a 30/50 data contract on Black Friday i.e. 30 November 2017 at Vodacom Constantia. 30/30 was loaded! I have submitted a letter of complaint, called the call centre and in daily contact with the store manager. I keep getting the response "they still busy investigating". WHAT ARE YOU INVESTIGATING FOR OVER 2 MONTHS? In good faith I purchased your Black Friday data contract. In bad faith you, VODACOM, are withholding 40G. I was given 20G anytime data for the month of February 2018. Thank you, but you have not resolved the issue! Why do you misrepresent your contracts in your marketing brochures? You are *****ING from a LOYAL CUSTOMER! Kindly contact me urgently as to resolving this matter.
