False advertising

I was looking to upgrade my ADSL line to a fibre line so I settled on the Vumatel Fibre SoftCap Internet Package 50/5 Mbps package (200gb data). The price quoted on the website was R749. I even took a screenshot of the page. This was less than a week ago. I requested a "call me back" so that I can do the upgrade. When the consultant eventually did call me, I was told the price was R899pm for the package. I explained that the price quoted on the site was R749. This was confirmed by the consultant and I was told they'll discuss the price discrepancy with their manager and will call me back. I'm still waiting... Then a second consultant contacted me and the same process repeated itself. Then a third consultant called me and the process repeated itself for the third time. Today I checked the Telkom website and lo and behold, the price has magically changed to R899pm for the same package. They obviously cottoned on to the problem after I made them aware of it, and decided to change their pricing on the website rather than honoring the original price. This is deceit...!! Fortunately I still have proof.
