Billed wrongly with content services as well as data packages

So during May 2020 my girlfriend which has been a contract client of Vodacom for as long as I Know her took out a new contract via Vodacom Direct call centre. She taught that she would receive two phones but in stead only one phone was sent. So she called and canceled the contract thinking that she would just wait and renew her contract at a later stage. Take in mind that her 24 month contract on both phones is already past the 24 month contract stage which she has with Vodacom. A week later the phone was retrieved back by Vodacom of the contract she canceled. Phone was picked up by Ram couriers and so she went on with the contracts which was now on a month to month basis. Cost she understood would have been on her account and she just waited for her account to be updated. She received the phone in the 1st week of June 2020 and the phone wss picked up in the second week of June 2020 by Ram Couriers. Then her bill came out for June 2020 snd her account was R200 more. That was still fine. Then in Jule 2020 we then looked to see cost again on the vodacom app and found that her bill has now gone up to with R1000 more. We then checked what happened on account and found that after the cancelation of her contract, content services had been placed on to her account for which she did not subscribe to. We then immediately called Vodacom to cancel these subscriptions because it was more then 3 subscriptions which took her bill up. The subscriptions were then canceled and she then waited again before she wanted to upgrade for the two phones. Then on Tuesday 2020-08-25 we had a look on her account again and found that her bill was now loaded with 3 gig of data, two 150 mb of data and again content services and tthis took her bill again up to more then R1500 since se canceled the contract in May 2020. She did not even sign up for these data and content serviceswhich was placed on her account and since se upgraded and canceled her contract, these services were placed on her account. Also since the csncelation she did not even get a invoice anymore and that is the reason that we had to log in to the vodacom app to look at her bill. Now she feels so angry with vodacom because she is sitting with a large bill because of these services that was placed on her account and is considering opening a ***** case against Vodacom regarding this matter. I would gladly appreciate it if you csn go in to her account and assist her with this matter because we tried calling and no assistance could be given. The lady did try from her side but could only do what she could. The number b weer longs to her which I wil fill in on the requist
