Bad service and empty promises from Telkom

I have order the S9 from Telkom, they have deducted the money already on the 24 April 2018, until today I did not received my device, I have started phoning from the 3rd of May to ask when I can expect to receive my device, every day they promise it will be tomorrow and I still did not received it. I have phone now again and the agent told to me that there is no record of my phone calls, I have proof from my side that I have phoned every day. He has given me the Ref number now to use for follow ups and also promise that the issue will be resolved within 24 hours. The Ref numbers are ********** 91A and ********** . The sales person who helped me, his name is Nozipho Nhlungu and also have promised everything will go accordingly. I just want have have my device by the end of tomorrow, as it is a gift form me to my mother for Mothersday, and this is on Sunday 13, and would not like to give it to her after and that is why I ordered it 3 weeks ago to make sure I would have it on time.
