Unhappy customer

I have been with Telkom, in fact, I should call it telkom because that's what I feel at the moment. I have been with them for over 5 years no idea why and every so often I call in to change my spend limit to 0 but it never stays there. I have complained so many times and never mind how I feel about it I find myself going back to them over and over again. Why do I do this to myself? I cancelled my Home LTE with them and went with a better provider and this has been the best idea I have ever had in a long time after such abuse from telkom. Out of the blue one of my numbers, limits were changed to R 2000.00 from 0 and as I asked to change it the limit will only be activated at the beginning of next month. How convenient for them that this change will only take place after another big change they will make. I wonder why they are still in business as clearly they care less about their customers in any way. Just like I have cancelled my LTE I am on my way to cancelling all my other accounts with them. Thanks for nothing Telkom no wonder why you are going out of business and all your staff is getting retrenched. Good luck to anyone who is still thinking to buy any telkom product or service, you will need it.
