Cancellations are impossible...

We have relocated to the Netherlands and my contract ends on the 16th of January 2022. I wish to cancel my contract and Vodacom is unreachable on all numbers. 082 111, 082 135, ***... I have been told that I need to give 30days notice and call into cancellations. Absolutely none of the numbers work for cancellations... I must add that this is most unprofessional as all these numbers are clearly stated on your website. Can Vodacom please arrange for an assistant to contact me urgently with regards to this cancellation as I would not like to renew my contract. My phone number is stated and is located in the Netherlands please add the area code +31 prior to dialing. Please do give me a call so that we may find a resolution together and finally place in a cancellation request for my soon to be expired contract.
