Takealot refuse to supply a product that was ordered.

On 7 March, I ordered and paid for a long-range walkie talkie from Takealot. A few days later the wrong product arrived - a cheaper walkie talkie. I promptly sent the product back asking for it to be replaced, to which I then received the following: "Unfortunately, the specific product you requested for replacement is no longer available from the original seller at the same price." Well, the thing is - this product is still listed on your website at the price I paid so I have no idea why you cannot supply it. Secondly, the onus is on Takealot to honour purchases completed via your website. I suspect at this stage that this is part of a **** and you are deliberately supplying cheaper goods in place of what was actually ordered. And one more thing - great idea to cancel all forms of communication to your company and provide a help system that is more than useless except for a select few inconsequential queries.
