RUDENESS, CONDENSENDING MANAGER AND MISREPRESENTATION ON A PRODUCT

I bought 2 tablets from Checkers in which a slip was provided. No T&Cs were discussed nor contract. 1 froze and 1 did not charge, I returned same 2 weeks back where I was assisted by Mpho is condensing, disrespectful and talk over a person. He fatly refuse to help advising that it was my fault, when asked him as to how he came with such decisions there was no answer. I insisted that they must take the phones. My question is does Checkers now sell irreparable products? Why was I not advised before I buy the product? What happened to documents for on T&C/ explaining such when selling products like phones? What happened to warranty as these phones only worked for 5 days. Was I given full information in order to make a decision as a consumer? The answer is no? I followed up yesterday as I was told that Mpho is a manager of some company that runs these phones. Why is Checkers not explaining this to us as Consumers so that we can buy them knowingly very well that they are discharged from liability. What is confusing I have Checkers slip but the phone belongs to someone else, how did this happen. Is this not misrepresentation? Today the so called rude manager Mpho calls telling me that his manager told him to tell me that they will give me 1 phone. Which manager is this now? Checkers or the sub- contractor / the company that surfaces once you complain. I requested him to tell his manager to give me the T&C conditions signed by myself and /or explain to myself as to when this was explained by them. He has decency to tell me to "Listen", am I his child or property? As this was not disrespectful enough when I told him that I refused to be undermined, disrespected by him, he kept on talking over me. I ended up telling him that I refuse to speak to him and he must request the same person who made such decision to call me. My question is who did I buy this phone from? How can I be led to believe that I am buying phones from the reputable company (Checkers Hyper) then all of sudden surface another owner of the same products. Right now I am confused and very angry at this situation. I am expecting Checkers to resolve this as I bought the phones from them buy furnishing me and answering the following: 1. Do they sell products with no warranty? 2. If they selling the products like phones, are we not supposed to get findings from their technicians or are their sales people qualified technicians? 3. How would sales person/ manager / technician (Mpho) come to such conclusion that I was at fault without even checking the phones. 4. How did I get to be apprehended by their employee as a small child, Is this the practice. 5. Furnish me with a document that I signed with T&C that when I was at fault I will not get a replacement and/ chance of repairs for a phone was bought 1 month ago? The question is if all this was discussed and explained would I have bought this phones? The answer is no.
