Telkom call centre sales - DON'T

Ordered a Dell laptop through the call centre. Agent clearly mentioned that they have stock and processed the order. Funds were deducted the very next day then got an SMS with a "tracking number" stating delivery within 3 to 5 working days. The tracking number didn't work so I called back and they said something is wrong with the courierit website. Called courierit a few days later and they said there's no such order. After calling the call centre again the agent says she doesn't understand why my order was processed since they don't have stock. How does Telkom make up a tracking number, send out an SMS saying clearly expect deliveries within a few days when they don't have stock? How are they so fast to debit your account and then say there is a refund process. Spoke to Zandile, the "boss" , after a few huffs and puffs she said that's their process and she advises I cancel and go to a store (what I should've just done in the first place). Definitely not a Telkom store. I definitely advise never ever purchasing anything through the call centre. What a waste of time will be canceling all other telkom products too. There's better stores out there.
