Faulty Handset

I bought a handset from Edgars in January 2015 on my Edgars account. The handset was used by myself not even for a week and unexplainably just went blank screened when I took the handset to the supplier I was told that it has a fault and will have to booked in for repairs. I was told that they would handle repairs as part of the service offered and by my surprise I was sent to a Vodacom outlet which was advised to be one of their partners. I had to take the handset there myself, upon my arrival I was told that the hand set has to be booked in, I agreed. A week later I was called to collect the handset and that the fault has been restored. not even three days later the handset done the exact same problem. This continued several times for the exact same problem all the while I was left to pay this handset on time every month without having the chance to actually make use of I what I owned. The fact that I have had this handset for over 10 months, barley made use of it and still continued to pay it with no reason to the problem nor have I received assistance in resolving this matter from either Edgars or their trusted retail partner Vodacom is completely unacceptable.
