No feed back at all - no communication at all

i am very much disappointed with Vodacom and the level of service they render and the way they dont care about their customers as i am very much frustrated cause i havent heard a phone for at least now a month or two if i am not mistaken and still no one from Vodacom has communicated a thing to me besides getting help from Samsung SA and believe me thats where one gets a professional, level of service from cause ever since i had to ask Samsung SA to assist me or help me with my concern or problem atleast something is happening but i am a bit frustarted as theres a lot of things a casanot do anymore because of my device not being available this long let alone doing banking as well as communicating via my phone when doing business, so now i dont know what to do or weather i should get myself another device and cancel the contract as well as selling all my family Samsung phones with Vodacom and go buy it directly from Samsung store as we are the family of S4mini for my small son, S4 for my elder son, S5 for my wife and i had an S6 which i owned for 3 months and the rest of the time its been up and down with Voda repairs until 2day as it still with them and i dont know what to do anymo
