Putrid Service... I NEED ANSWERS!!

Putrid Company. On the 28th Feb I paid my bill and sent proof to the accounts department. And then received a letter demanding payment. Okay fine. I then sent through the proof of payment again on 17th March. I then got an email from Tumi from Collections that was absolutely rude and straight up told me I didn't pay and switch off my internet. I lost money at work that day. I then spent money on airtime trying to sort out this issue and got through a nice lady who helped me in Accounts and transferred me to Ruth Kekana and she confirm she found my payment and everything is sorted and switched on my line. A few days later I received a letter of demand asking for double payment and switch off my line again... AGAIN!!! I have been without Fibre for almost a week, I am at risk of losing my job, I have been losing money and when I try to call the agents are so rude! I spoke to Naledi Masuku on webchat, instead of empathizing and understanding, she shows attitude and NOT ONE APOLOGY FROM HER OR THE NEXT RUDE AGENT LERATO IN ACCOUNTS... my wife has anxiety and stress and this whole situation is making it worst BECAUSE VOX CANNOT FIND MY PAYMENT! I then get told my case is Allocated to Dianne Van Zyl because never answers the phone and is always on Lunch... I WANT MY PAYMENT FOUND AND I WANT COMPENSATION AND A RESOLUTION IMMEDIATELY FOR THIS DISGUSTING CUSTOMER JOURNEY VOX SHOWS US PAYING CUSTOMERS!!
