Galaxy S7 promotion was a lie

I have written to customer care on the 25th of April regarding my complaint about not receiving a wireless charger with. My galaxy s7 device which was part of a promotion Vodacom had with the initial launch of the galaxy s7 on the 11 of March 2016. Which also coincides with the date I received my handset. The wireless charger was off handed on my invoice slip at the till at Vodacom 4U store in Clearwater mall. Its now almost 2 months later and I have no feedback whatsoever from the store only that they would call me if the chargers are in Stock again, which is strange as when something is advertised publicly and the provider can not produce said products even on the very first launch date of a promotional device in their store surely this is against the consumer protection act! The customer care department seems to be buying for time as well as I only get emails back to me saying they are investigating the situation still and that feedback has been requested. I have send numerous emails that got me absolutely no where. I'm very impatient now, if vodacom can't provide the stock give me a voucher that I may buy the charger at the samsung store as clearly vodacom has not intent on giving me the charger as from what I understand from the two vodacom stores in Clearwater mall the wireless chargers were never received in store regardless of the the promotion that vodacom had running. Vodacom 4U staff admitted to having over 40 customers with the same problem as I have. I wonder how many have even gone as far as I have to get the charger out of Vodacom as the charger was part of the promotion! Please now after I have sent numerous email and periodic visits to Vodacom 4U store in Clearwater mall to get some sort of feedback I am now posting to HelloPeter.com to see if someone can actually attend to the matter as I am at a point of lodging a more serious complaint against Vodacom for false advertising! My complaint reference number as per the emails: 001CFaBHXQ1BXHMR
