Customer incorrectly billed

Dear Telkom Customer Service,

I am writing to formally request a full refund of the overcharges on my account. Since upgrading my phone in April, I have been incorrectly billed for both my old contract and my new one. Despite multiple inquiries and proof from the iStore that this was indeed an upgrade, Telkom insists it was not. However, I followed Telkom’s advice and waited until the contract end date, and I did not authorize double payments. The total extra deduction across May and June exceeded R500. This is a significant amount, and I expect an immediate correction and full reimbur*****t. Please escalate this issue urgently, as I will be forced to pursue further action if it is not resolved promptly.

Sincerely, Phakamile
