No reasonable answer from Cash Crusaders after a week

No proper feedback from Cash Crusaders .I posted here on Friday morning regarding an issue we are having with the Cash Crusaders Chatsworth branch. Below is my message :

Recently we purchased a 7 inch tablet from the Cash Crusaders Chatsworth store. When we took it home and tried to use it, we noticed it was faulty. Called the staff on the phone, who asked that we bring it back for repair. We then went back and handed it in , and after about a week or 2 , were called and asked to collect . We collected and took home , and found that the tablet was not repaired properly( Still faulty) . We called the store again and were Again asked to take it in , which we did . It was "repaired"and we were once again asked to collect this. We went and collected , took it home and used it. Worked for a few days and went off , refusing to come on again. We called the store to complain and were told that we had to take it back Again. My dad took it back to the store and was told that it would be sent for repair Again !! We were called a few days ago asking us to collect it. Apparently someone from the store said it is more than 7 days , so we couldn't return this , and said that only after the 4th time would we receive a refund or another tablet, and we will have to accept this repaired tablet. Does it seem fair on the shop to expect us to keep going back , costing us money , time and inconveniencing us every week or so ? I am very close to going the legal route on this. Its not Just about the money , Its about the principle ..Those people seem to think we can just afford to keep going back to the store every week or so . Really have had enough from Cash Crusaders ..

I was expecting an answer by Monday / Tuesday on this . Its exactly a week later and nothing . All that I was told was that this matter would be escalated to the Operational Manager and Regional manager for resolution . And I was given an apology .Thats where the "feedback "ended. Is it at all possible for someone to just come back to me with some positive feedback ?
