USELESS VODACOM CONTRACT UPGRADE AND BILLING DEPARTMENTS

I was on hallopeter.com at the end of February 2016 bitterly complaining about the **** service I received from Vodacom. Just to recap: I upgraded my cell phone contract on 5 FEBRUARY 2016 to a UChooseFelxi 200 Top-up package (R420 per month capped) which has capped SMS's, call time and Data Usage. On 18 February I received and SMS from Vodacom complaining about "unusual high usage" of R2 262,93. I queried this and received reference: 1-***. Twice a week I followed this up but had no answers out of Vodacom. On 26 FEBRUARY 2016 when I queried this again the account was R8 173. I opened a case of ***** (SAPS Case 214/3/2016) against Vodacom, complained on HalloPeter.com and went to Vodaworld self. Only them was the matter resolved and was I given a credit on my account. Remember I have a contract with capped data/calls/SMS's which only costs R420 per month. Once used up one has to buy top-up data/call time/sms's. Yet, on the 29 APRIL 2016 I received a fat R 4 478, 40 bill from Vodacom which they credited against my Credit Card. When I queried this I was told I used R3 509,92 (ex VAT) on Data Usage. After 90 minutes of the phone where I was put through from the one department to the other I ended up at "Customer 3D" services. The lady who took my call acknowledged that Vodacom passed a R7 284 credit for the blunder Vodacom made with my account in February 2016, but said the data usage for March 2016 was my problem and stood. She said Vodacom only upgraded my contract on 1 APRIL 2016. I complained that my upgrade was approved by Vodacom on 5 February 2016. I have a signed contracted dated 5 Feb 2016 to prove this. I stood right next to the consultant when Vodacom phoned him to give him the authorisation code to effect the upgrade. Why has it taken Vodacom 2 months to change the details. Customer 3D insists it is not Vodacom's problem. I am not satisfied with this as Vodacom is in breach of Contract and I demand a refund of R4 001,31 (R3 509, 92 plus R491.39 VAT) paid back to me in cash. Why has it taken Vodacom 2 months to update my contract details? Are they that *********** in managing their Customers' accounts, or Vodacom too big to actually care about their Customers? I am not satisfied at all. Vodacom Customer 3D logged a Reference No. EC-04yo-2WP8JN for this query. How long is this going to take before something gets done? Again 3 weeks like in February 2016?
