Unjust Charges After Contract Cancellation - Request Urgent Resolution

I am writing to express my frustration and disappointment with Telkom's handling of my cell phone contract cancellation.

My cell phone contract with Telkom officially ended on 25 April 2025. I went to the Telkom store on 26 April 2025 to cancel the contract. At the store, I was assisted in calling the cancellations department, and I successfully cancelled my contract over the phone. I was informed that I needed to pay R958.10, which I duly paid on 27 May 2025.

To my surprise, I have since received an additional invoice for R1,424.62, which I do not understand, especially since the contract had already ended and I settled the outstanding amount as advised. This situation is highly concerning. I fulfilled my responsibility by cancelling the contract promptly and paying the amount I was told to pay. It is unacceptable to now be invoiced a significantly higher amount without clear explanation or justification. Kindly assist. I kindly request the confirmation that my contract has been fully cancelled. I requested that I will only be using the no which is ***, and I'm left with one contract of a ruter which amounted to R249.00. My contact no is *** My email is ***
