Two months going back and forth

i don't know who to contact anymore because i am still sitting with a problem that can not be solved. who can i escalate the matter to? the reason people take insurance is so that that they can have a peace of mind, in my case it has been nothing but grief. i even had to purchase a new phone while waiting for Foschini to pay out my claim. i think i have been patient enough since last year December. phone calls that i receive every week from them with no positive constructive feedback are just a waste of my time. if this is how clients are treated then people should know about my bad experience and also stop selling phone if its going to be a loss for another person. all i want is my phone i am tired of their stories.
