Telkom :Mampara of the year 2022

Wrong Billing from Telkom the month November 22, only discovered on January that did not pay my November 22 billing. Sent them prove that debit order went through during end November, went as far my Bank (FNB) told them my story and their(FNB) help me, to produce evidence and sent via email to them. I was emailed again for the December 22 proof of payment, sent it as well. Telkom is like Eskom not delivery the services that they are supposed to provide. Please help me here Peter, worst service provider for billing.
