Bad service and ***** - Vodacom

I have 2 complaints: Firstly I paid my account on 29/06/2018 at the Vodacom shop, received my account on 09/07/2018 showing that my account is in arrears. I phoned them and gave me an address to send my proof of payment. I did that on 09/07/2018 and up to date nothing happened, no call back, no reply. Receiving 100 calls a day to confirm my account is in arrears. When you phone then, nobody can assist you, putting your through from the one to another.... Secondly, I upgraded December 2017 and got a tablet for free with 500mg data for 24 months, the contract is for free and now someone at Vodacom did a migration to a u Count R165 paying line. I did not agree to a migration and nobody called me to confirm. I send an email to their ***** line on 09/07/2018 and no reply yet. I am not going to pay that line as I did not requested that. I am so furious with Vodacom, their service are so pathetic. No satisfaction at all with Vodacom.
