I am writing to formally lodge a complaint regarding a serious billing and payment issue on our Telkom account. We settled our account with Telkom by paying the settlement amount of R204.37, not once, but twice via EFT. Despite this, Telkom also deducted the same amount (R204.37) from our Nedbank bank account twice. In total, they have now received this payment four times. However, despite proof of payment being available, we are still being informed that our account is outstanding. This is completely unacceptable. It appears that someone in your billing department has failed to allocate the payments correctly, resulting in inaccurate account information and unnecessary stress on our side.
