Urgent: Contract Cancellation Issues and Unjust Billing

I am writing to express my extreme dissatisfaction with Vodacom's handling of my contract cancellation.

Here are the details:

Contract Cancellation: I canceled my contract on January 28th and paid the penalty fee for early cancellation on the same day.

Document Submission: I sent the required documents to the specified email on January 29th.

Follow-Up Calls: On February 1st, I called to check the status of my case. On February 10th, I called again and was informed that my data line was changed to prepaid, but my main number was not canceled. During this call, I was also disconnected after being transferred to a non-responsive line. On February 20th, I called once more and was told my case was escalated and a senior staff member would contact me. However, I received an SMS stating my bill for the month would be double my usual amount, despite having canceled the contract. When I called back four days later, I received a prompt message stating my number was blocked due to high call volume to ***. I was advised to WhatsApp *** or call *** at a cost of R2 per minute.

Issues: My main number is still not canceled. I am being billed double despite canceling my contract. I am being charged to resolve an issue caused by Vodacom's poor service. This situation is unacceptable. I demand immediate resolution of my contract cancellation and a refund for any unjust charges. I expect a senior staff member to contact me directly to resolve this matter.
