Cannot get anybody to help

On or about the 14th December 2015 I ordered telephonically a data bundle (R216Z Router with LTE sim and 2GB Data per month). Just for info, I am a Vodacom contract customer for about 20 years now.They approved my deal, but sms me to inform me that they do not have stock! On the 24th or 26th of December they sent a sms to let me know that they will now deliver soon. I phoned and let them know that I am now away for a few days and will only be back on the 11th January 2016. Can they deliver then? I was informed that they cannot wait that long to deliver and that they will now cancel the deal!! I accepted that. On my return I went to a Vodashop in Cresta and ordered the same bundle. Stock was no problem. The problem now is that they cannot do the new deal because the previous deal is still not cancelled. This is now almost 4 weeks and I still do not have my data bundle!! I have phoned Vodacom customer care line and somebody called Linda said they will cancel the deal but it will take about 5 working days! So I have to wait another week because they cancelled their delivery! I just think this is the worst service anybody can receive from a supplier and nobody cares!!
