Someone at vodacom made a mistake and added R15 000 on my account...I did not pay the R15 000 because it's not my mistake... I paid the amount that i had to toe Keep my services active but still i have to phone vodacom 7 to 8 time's a day just to unlock my phone's...I am the owner of a company and i can't afford my phone's being off i have spoken 2...3 different managers and still no assistance was received from them...</p>
