Poor Service Delivery

Good Day To whom it may concern I hope my complain finds you well ,please note that I am not well with the vodacom service ,in January 2019 I called the contract department to cancel my contract because I was done paying Vodacom.So the person that was helping me advised otherwise ,saying I shouldn't cancel the contract but pay less .Meaning I will keep my insurance and receive airtime and data ,she then asked me a question of why do I have so much data on my sim card.I explained to her that I misplaced my card and anyways I am using Telkom as my SP,she told me they will send the sim card to me within 7 working days with that 900 airtime I had.I have been waiting since from January to this day being the 31 May 2019.I call Vodacom everyday regarding my matter,they keeping saying sorry we will send the card ,we will take your matter to the team leader ,the team leader will contact you.The last time I called was last week,they said I will get the sim card but not with the airtime,it will be like I am starting a new contract .So for the past 4 months I have been paying for what .I mean they have been debiting my account every month without me using their service .I need help here.
