Unfairly Treated - No return calls

End of January of 2020 a vodacom consultant called me informing me of my free device (phone). ask me whether i would like to continue with the airtime as provided for the 24months. I responded by saying "no i would not want to continue seen that it was a free phone that came with my contract device. Since then i also thought why i'm paying so alot but never worried about it because i thought it was all my devices. But then during the lockdown period i started to get worried because the amount never decreased and according to T&Cs from Vodacom once your contract ended you only pay for the data/airtime and not the device. I then checked my wife's vodacom app on her phone because the app can't download on my p20 lite. On the app you are able to check all your device phone numbers and how much you pay for each. the phone was only used by my 5yr old son now and then on airplane mode watching his free youtube videos because he also has a tab that he watched his videos on. but that is when iv noticed that i'm being charged for a phone that im not making use of starting with 066. that is when i called 082135 on 30/05/2020. the agent who picked up the phone listened to my inquiry but transferred the call to cancellation office. i then spoke to a Wilson, I again had to explain myself. Wilson informed me of the T&Cs of when i signed for the contract. My words to him were, T&Cs i clearly understand but iv never signed for T&Cs for a free phone that came in the box with the device that i actually upgraded to, the 082 number. Disagreement went on between myself and him and then i say that i will take you to hello peter because you are not satisfying me and saying that it was my responsibility to cancel the promotion (free) device that came with airtime (066) with my upgraded device 082. I again disagreed with him and he said that he will escalate the issue with his supervisor and will ask the senior person to give me a call. As time went by waiting for the return call from the supervisor and had to call myself again i think on 6/6/2020 and a lady agent picked up the phone, i think her name was thobeka. I explained to her the situation and said that it was unfair towards me that no one came back to me. she told me that she will escalate the matter back to Wilson and ask him to give me a call to apologise and also credit me (because i was again billed the full amount). then i waited again for a call. i then had to call again on monday the 22nd (±16days) after my call with Thobeka, then i spoke to a guy agent called Luyanda (spelling) and he also aplogised on behalf of Wilson but he can only cancel the debit order going off for the free phone of R110. I will have to call again and ask to speak to Vodacom Office and to speak to a manager. Most of the agent working from home. Today (24/6) i called again and spoke to annalie and she also apologised on behalf of those who was supposed to get back to me. she assisted by escalating the query to whomever and have requested that i get all my refunds and an apology. I said to her i hope someone will call me because im now tired of calling you every time and she confirmed that someone will come in contact with me. I so tired of fighting for money that was not supposed to be deducted or that i was not even aware of.
