PATHETIC SERVICE ON SAMSUNG PHONE

My microphone on my Samsung Note went technical and I had a cracked screen - sent it to Vodacom Canal Walk to get fixed. 2 Weeks later, they advise me to collect it. Get home, switch it on, screen fixed but microphone still broken and not menu and back button broken (which is wasn't when sent in)! Take it back to Vodacom Canal Walk, ask them to fix microphone and now menu and back button. 2 Weeks later, they advise me to collect as phone is apparently fixed. Get home, switch on phone, back button and menu button working, microphone still broken and now aerial is broken!!!! Take it back to same shop as I may not use anywhere else as there is a repair warranty now with shop, manager explains he will get it fixed personally!<br> 1 Week later, they advise me to collect, microphone working - YIPEE!!! BUT NOW AERIAL STILL NOT WORKING!!!! Now they ask me to send them a email about my complaint - which will go where???<br> I NEED A PHONE THAT WILL BE FIXED PROPERLY - IT IS MY BUSINESS PHONE AND I AM LOSING TIME AND MONEY THANX TO VODACOM/SAMSUNG PATHETIC SERVICE!!!
