Still awaiting my product, more than a month later.

I had purchased 2 clothing rails from Merkado early September. Merkado had incorrectly priced these items. They then decided to try getting out of the sale by saying they ran out of stock, even though at the time of purchase they had stock, & still do as per the website. I sent them an email, after numerous failed attempts to get through to their customer care line. Merkado then called me a few weeks ago, where a woman spoke to me about their mistake with pricing, but agreed they owe me the product, as per the consumer protection act. She then advised she would call me back, but now a few weeks later, still no other contact has been made. It has now far exceeded the 21 max days to deliver, & is in fact heading to the 2 month mark since my purchase. I would like to get my products delivered. Please advise. Your customer care line is clearly a dud.
