Very Very Unhappy Client!!!

VERY VERY DISGUSTED!!! We were billed with R2800-00 for something added to our account which we didn't gave permission for but has to pay for!!! If you phone the Customer Care Department NO ONE can assist you nor give any answers on your questions. Out of the blue this was added to our account and all of the sudden my one contract run out off sms`s calls and data like in by the 7th of June 2018 with us doing the same as the past 5 years. We phoned the Customer Care Department like in 30 times and once again NO ONE can assist/help/give answers. But we have to pay no matter what nor the bad service we get!!!!
