No communication regarding delay i upgrade

<p>I did an online upgrade on 13.03.2017 because the lady on the phone told me that there is stock available and I should have my phone by wednesday. This was not the case.</p> <p>On wednesday I started calling vodacom but every time I phone there is another excuse either their phone lines are off (REALLY?????) or they have a back log. the reason I upgraded online is because they stated they have a phone in stock otherwise I wouldve gone to a store. I have spoken to a lady that apparently spoke to team leader at confirmations who promised to phone me on 16.03.2017..... he didnt, I spoke to complains department who promised to get back to me 16.032017....they didnt, Ive spoken to customer care who refused to assist because its not their department, I emailed headoffice and received a reply to contact customer care? Can someone assist me this is not acceptable a customer can not be **** to or treated like this. I spoke to a gentleman at vodacom upgrades this morning who stated that my phone is at RAM couriers but after calling RAM with the tracking number they stated that the phone was still being held by vodacom. Ive posted on vodacoms facebook page to desperate to get some sort of assistance they rep**** and asked that i email them. So i sent an email on 16.03.2017 but have not had any correspondance from them yet..... what does one do?????????</p>
