Misleading customers, lack of knowledge Terrible service

I have done an online application , 3 weeks ago, first week I received an sms giving me a tracking number also notifying me that it will take me 2-5 days to receive my items. I called the courier company. They told me that Eskom haven’t sent nothing to them. So what is the tracking number for????? Mislead clients???? I then call the call center on 10213 was sent from pillar to post.... sent an email... but not respond to date..... til today no joy... I have exhausted my resources.....
