Phone delivery unsuccessful - twice. I am not paying for the delivery!!!! Cell C - what a dissappointment yet again!!!

I renewed my contract with cell c. I received phone call from cell c on Wedn 8/12 after waiting over a week for my phone. The kind lady apologised on behalf of cell c saying the person handling my upgrade did a mistake (no surprise there!!!) .....she is handling the process now and she will make sure I receive my phone by Friday 10/12 and I will receive a phone call when courier company arrives with my phone. I received no call. But when I arrived home, my neighbour said I just missed the courier. The courier said he will return. Only after 5pm I realised he will not come back and I phoned cell c. Cell C said they cannot do anything, because the courier company closes at 5pm. Today, 13/12 I phoned cell c again to ask when will I receive my phone. Customer care said the driver phoned me twice on Friday - not true. As I was on the phone with cell c, the driver arrived. My neighbour asked him to wait as she is calling me. When we arrived back at the gate - he was gone. He did not even wait 2 mins. I asked the customer service person to follow up but she just said she is the wrong department she cannot help me. I phoned cell c again for the correct department - they said the driver made a note "he could not wait as he had other deliveries" - he barely had to wait. He also never phoned! I googled the courier company myself as cell c totally useless to assist. No one is picking up their phones at Courierit at ***. I phoned cell c again asking to speak to a manager, the one lady made me wait 20 mins without any correspondence. The other customer care service lady, Lesego, just kept me hanging. I explained to Lesego the inconvenience, and after the ordeal she gave me the nr of the courier company - same nr as above!!! When I explained that this is cell c's responsibility to follow up, she just said "well we cannot phone out, you have to phone them" and she just kept me hanging......no correspondence, no answer, no explanation, no assistance.......She said she is making a note that the courier company must deliver tomorrow......but what guarantee do I have???? Just waiting for the call that will never happen??? And then be liable for the courier costs for my phone to be delivered? At this point....I have handled so much inconvenience, so much hours spending on phone with cell c. Totally useless!!! and ***********!!!
