Telkom

I am not sure how Telkom confirms that the phone i ordered iphone 15 is not in stock that is why i have not received my upgrade but sends me an invoice billing the same phone NOT RECIEVED this was reported case number *** now i have just received and invoice of over 20 000 for WHAT? I DO NOT KNOW !!! someone from Telkom needs to get hold of me and sort this out as i will NOT be paying for something i DID not receive this is really absurd.
