Unfair Billing and Threats Despite Telkom’s Own Error

My mother’s Telkom account has already been paid, yet Telkom debited her account twice for the same monthly payment. Despite this clear error on their side, they are now threatening her and claiming she still owes them money, instead of resolving the double debit and processing the refund they owe her.

We have proof of payment and bank statements showing amount that went off. It is unacceptable for Telkom to treat customers this way!! We want this resolved immediately.
