Ref *** - Day 8 and my account is still blocked but paid up to date

Ref 1- ********** ********** - Day 8 and my account is still blocked. When my mom opened up an account with Vodacom last year you somehow added her number to my account and proceeded to bill me for her number (this is completely *******) and after months of trying to separate the accounts you then proceed to double bill her in November 2017 on my account (her number is a set amount every month) You agreed to the double billing and incorrect charges. (I had reversed the amount of R1781 which was incorrectly billed on my account and then went instore to pay my set amount of R770 on my number) Not only do you keep the incorrect double billing charges on my account but you still keep my mom’s number under my name and my account. Come January when my debit order is supposed to come off it doesn’t come off. You then proceed to block my number claiming I owe R2870?? I have a set figure every month , you are still trying to charge me on the double billing which was incorrect in the first place and you still have my mom’s number under my name plus you have separated her name into another account! You need to rectify your accounts and take her number off my name totally, she had been making her own payments to you for her number since beginning of December. You also need to take that incorrect double billing amount off my account and stop accumulating it each month - it was agreed it was an incorrect billing!! The only thing I should owe on my account is the R770 for my account which has now been paid. Stop treating me like I am in the wrong – this is disgusting!
