Telkom dont accept proof payment

Made a payment and still doesn't reflect in telkom account and now i am being charged double I even emailed proof of payment few days ago even with proof of payment they cant help. Telkom font accept it when you send proof of payment receipt even if the money doesn't reflect in they account immediately but at least proof of payment is there but no they dont work like that you must wait 24 to 48 hours for them to receive payment and only than will they assist you.

that is poor service if you ask me.
