Lack of customer service

This Is now the second report I am sending in. with regards to the first report I received a phone call before Xmas advising me that my complaint is being dealt with and I could expect feedback very soon. Well guess what we are now over a month down the line and no follow up has taken place. Vodacom made me even more angry yesterday with regards to how they spoke to my mom. So now I have 4 issues with Vodacom. I have picture proof that your advert board says Guaranteed Free gift with every new contract or upgrade, and guess what we never received them. We were also supposed to received 2 wifi extenders. Vodacom apparently never had stock and they were going to call us when they arrived and guess what we have still not received a call. Then with regard to my cochlear and being told the Samsung S2 gear cannot be obtained with my contract when I upgraded to then find out 2 month later after purchasing a Samsung Gear 2 that does not work properly and I still miss half my msgs and phone calls. So once again thanks to Vodacom we are suffering and my life has not been made simple like it would've been if I had received the Samsung S2 gear added on to my contract. I await prompt feedback
