Telkom was my worst decision

I have a SIM only contract with telkom. We had agreed on the billing to be on the last day of the month. But telkom debited me on the 25th of January for my first billing of the contract. Instead of the last day of the month. On the 25th of January they debited my sons school fees money and on the last day of the month the transaction bounced. My problem is that because of telkom having debited me on the 25th the second billing on the last day of the month bouncing on their systems when I make calls they only have the bounced billing on their system and not the initial billing that was done on the wrong date and was successful. Because of that I was immediately for the following month taken 2 collections which now ads 100% extra on the amounts that they are supposed to bil from my account. Month after month I make calls to get this rectified to no avail. The worst part about this is that every month I am being charged twice the amount that I'm supposed to be paying just because of the mistake the telkom made in the first place. I always have to call telkom about my query all the call centre agents tell me one thing that they only see the billing of the end of the month. And that they do not see the one on the 25th. They all tell me to send my bank statement of that month 2 the telkom collections email address and also some of them to their personal telkom email addresses. I have done that so many times and there is never communication back to me as to whether they see that the billing is from them and that what will be the way forward from their own. My SIM card has been locked for the past 3 months now. And what pains me the most is that I created the SIM card so that I may be able to do my school assignments and examinations with unisa without having to worry about data bundles all the time. Then came the time when I'm supposed to be doing my assignments submit them and also write my exams I have to be buying small amounts of data bundles with the little money that I am left with full stop as we speak now I have been making monthly payments of the initial amount that I am supposed to pay excluding the extra amounts that I'm being billed. My biggest problem is that according to telkom I am supposed to pay the extra penalties that are added on my account of which those penalties are created by telkom having made the mistake of billing me on the wrong date as opposed to the one that was agreed on. I have been trying to get telkom to be accountable for the wrong billing and take my account back to the normal payment without any penalties, because the penalties were a mistake made by telkom and not by me. I am very angry and have been telling everyone not to take up contracts from telkom or buy sim cards from telkom because they are not reliable. I am still asking why is telkom you wanting me to pay for a mistake that was made by them. None of the call centre agents were able to give me a solution except for them asking me to send my bank statements over and over and over and over and over and over again without any communication or feedback back to me at a later stage stating whether they can see the mistake and I willing to fix it or what is the way forward. I'm very disappointed because I had to come in there talking to so many people then now they have let me down. I cannot even trust telkom enough to be a line that I use for my new business because by the looks of things it will clean out my business bank account. I am beyond disappointed and I'm still not willing to pay for the mistakes that telkom has made. I just wish I can talk to someone who is not a call centre agent that will listen and fix this problem without making me pay more money than what I'm supposed to. If you are looking into a contract whether it being a phone contract or router contract or SIM card contract, beware of telkom ******** you like they're doing to me right now I am having to write my exams with data that is always getting finished and cutting me during the exams because of telkom. Hey I'm just hoping that I will not fail my online exams because of telkom because that would be the worst.
