URGENT ASSISTANCE

My Samsung cellphone has now been broken since last year. I have sent it in 4 times to my nearest accredited Samsung repair shop- This trip takes me 80 minutes in total both ways to get there. My phone is fully insured, the first time I sent it in it took over a month to get back, came back, and only worked for one day then the microphone blew again. This has now happened 4 times. Long story short.. The last time I went back into the shop and they told me there is absolutely \nothing\" wrong with the phone and there is \"nothing\" more they can do for me.It has now come to a point where I have been paying my insurance as well as my phone bill every since month without being able to use the actual phone and now DEMAND a new phone.I have wasted my money on this phone and insurance as well as all the petrol wasted to drive to Richards Bay MTN shop- I should get reimbursed for this?????I demand something is done about this URGENTLY. My son was recently hospitalized without his school being able to contact me, this is becoming to affect my life in a VERY BAD WAY. If its a problem with Samsung or with Vodacom I need answers. I refuse to make any more of these trips up and down!!!!"
