DISGRUNTLED , DISGUSTED AND DISAPPOINTED.

I have purchased campmaster tent from Makro cornubia on 13 March and used it a week later 20th just to find it leaking. I took it to returns department on 22 March at springfield branch and was told due to policy I can't return it cos it's used and does not have a guarantee . (How would I know if the product is defective without using it). I was told to take it back to cornubia branch where I purchased it. At my own cost I did. The tent was booked in to be assessed by the manufacturer. But the exact same type tent was purchased by Mr/mrs K and N Perumal on the same date and their tent leaked as well. They took it back on 26 March to Springfield branch and was offered choice of another product or refund. They chose refund and was given a voucher to cash at tellers. How is Makro policies different to customer. Why was i treated differently? Why did I not get the same assistance? The Service I received is not acceptable. Makro is a chain store, and I should not be running around to a specific branch for a defective product returned within 14 days. I want a full refund and compensation for the inconvenience and terrible service given to me as a client. If i do not get feedback today , i will be reporting this to the Ombudsman and all social media platforms. Call me on *** , Name : Trevor pather , email : *** .
