WORST SERVICE PROVIDER EVER!!!!

Vodacom has suspended my account as they said that i haven't paid and have an outstanding balance. I am sitting with the proof of payment in front of me. I will be taking this further as i am fed up with this service provider!!!!!!!!!!!!!!!!!!!! They are cheating consumers with contracts and making false promises, this is my first contract and i am hating every moment of it, im spending more time on the phone with customer service than i am actually using my phone for personal use!!!!!!
