Its their way or no way - maximum arrogance!

So, they show cat sand at R850 on the Takealot App with 14 in stock so I order it and go to checkout. However its now shown at R999! I go back to the product and its still shown at R850 with 14 in stock. I cancel the order and write to Takealot advising them of the problem. Long story short over 5 rounds of email - there's nothing they can do about it - I must pay R999 and at no time do they actually listen to me and try rectify the issue. In fact they said I cancelled the order so now its R999. Only reason I cancelled was because of the price difference! Unbelievable arrogance - not from the poor customer care lady but the process that she has to follow - "AT NO TIME ACCEPT LIABILITY, BLAME THE CLIENT AND DON'T HELP THEM"!
