Most Pathetic Service ever

At this point of time I don't know who's the most pathetic - Sony or Vodacom... A two month old phone, Sony Experia XZ2 is faulty - Charging port doesn't charge - I take it in to Vodacom Repair Shop Alberton who's service wasn't bad but got the phone back with a mother board swop (4 days) ?, so what happened to the charging port problem? Charged that night just to wake up to a phone not charged at all. Took it back, stripped myself and took it in to SSS Repairs in Boksburg myself and waited another 3 days for the charging port to be replaced (again??). So got it back eventually just to wake up to a non charged phone again ?. Faulty Charging Port, AGAIN!!!!!!! Took it to the Vodacom Shop in Centurion who send it away AGAIN!!!!!! NOW 6 DAYS LATER!!!!! In the mean time I'm paying 8 x Vodacom contracts on a monthly basis with NOT 1 late or missed payment!!!!!!!!!! So everyone is protecting you, shouting at me, refusing to answer their phones, but who is protecting the hardworking customer's rights????
