Still no response. Disgusting Customer Servuce

I think this is a absolute blady Joke. Vodacom is supposed to be supportive of the deaf and hearing impared but yet they dont bother to respond to my messages/emails/complaints. Like I said previously I am deaf and make use of a cochlear implant. When I renewed my contract in September 2015 I asked if my upgrade included the S2 gear and if not how could I obtain one through Vodacom. I was told my package didn'tinclude the S2 gear and that there is no way I could obtain one. To then find out later I couldve had it added to ny contract from day one. With me being deaf the gear is not a want or a luxury its a necessity because I miss alot of messages and important things not hearing my phone. With the gear I am able to not miss important calls or messages. I know for a fact it would assist me as I was guven the sony gear by sony and it made life so much easier. If I was not mislead and **** toI would not be battling the way I am. Vodacom has let me down in nore than one way the past few months and I am extremely disgusted. I honestly feel if vodacom are so supportive of deaf people they would come up with a solution to assist me in obtaining the S2 gear to assist me as a deaf person
