Batling to close expired contracts. I also have pending deals that I did not order.

I have been struggling since 20 October 2020 to cancel three contracts (all of which expire on 9 November 2020). The contracts are as follows: a 500 megabyte data contract that came with a tablet, a 10 gigabyte data contract that came with a Huaway router and a uchoose flexi 120 that came with a sumsung phone. Today I found out that there is a pending sim only deal on my name also which I did not order. Further more, I have ordered a Mecer Guru pro on a 5 gig contract on 20 October 2020 and this order does not exist according to Vodashop Langeberg mall. Please cancel all my contracts and pending deals. Thank you.
