NO ACCOUNT AFTER NUMEROUS REQUESTS

I have been battling to receive an electronic bill from Telkom for years! I complain and then a bill arrives for a short period of months and then suddenly I stop receiving them again. I complain again and a few more arrive and then they stop again. How difficult can it be to tick a box on a computer programme to ensure a loyal customer receives what they ask for? I want to pay my bills on time but they don't want to notify me of what I owe so I end up guessing an amount each month to pay just to avoid being cut-off!! This is absolutely ridiculous and pure incompetence on Telkom's part. Do they not want to be paid?
