Poor customer service regarding repair logged

I've logged a return for a product that I use once that broke after the first use. It's a R2500 coleman event shelter. My exchange /repair was declined even though the product has a 12 month guarantee and it was only 1 month old. This was one month ago. I am still sitting without my gazebo but takealot has my R2500. I've spoken to various call center agents and the manager promised to phone me 4 days ago. Every time I phone the 'escalate' the matter. Worse part is all the agents work from home and therefore when calling you can not be transferred to a manager. I don't know what to do further as I've ran out of ideas. Please think twice before making use of takealot.com as they are quick to take your money but they don't deliver when it comes to customer service or repairs. They latest information is they've lost my gazebo. What's next??
