Urgent refund on ****** money

I need an urgent refund for money i were paying which i did not give my consent to so this is ******* and ***** and theft. Got called on 26 Feb at 08:58 the morning from an vodacom agent with the dealer ID VDCOM AND USERNAME : JAGGK001 Stating clearly to change my package for my contract with a lower amount but more benefits. This call can be traced and i will take matter tor court as i even repeatedly asked the agent specifically about the amount. My original amount of 1088.98 i signed for Then became R1302.98 which i did not and I repeat I DID NOT agree to was then debit from my account. I went to vodacom store and they told me i need to wait few month before they can fix it Resulting in me paying this R1302.98 for 5 months. And minus thr extra money from my original amount of R1088.99 it is R213.99 extra every month. And i say again i did not give consent to this. I also waited for the investigation staff to call me back and they never did! But the amount of R1069.95. Need to be refunded immediately to my account as this was ****** from me!
