Telkom 1TB bad experience

Bad experience. I am currently on a 120GB month to month LTE contract with Telkom. I wanted to upgrade to 1TB LTE month-to-month contract. I first went to their store on Saturday 12th September 2020 and I was told to go online. I then called their sales deportment on the same day and my order was cancelled two days later because I chose the wrong option. I called the sales department again on Monday 14th September 2020 and I was told to do it in-store because I have a multi-sim. I called their sales sales department the 3rd time and I was told to go in-store. The next day I went into the store and I was told to go online. I then related my story and the people in the store they then called their sales department because this product can only be bought online. It is not offered in-store. I spoke to one of the consultants over the phone (in a Telkom store) only to be told that my area is not covered under this particular product (1TB month-to-month). I have been using Telkom LTE for over 8 years and it has been working very well. I have excellent 4g coverage. This I don't understand. The website is also not clear on this. It only states: subject to coverage. There was no coverage check when I upgrade to 120 GB.

I am not happy with how Telkom handled this matter. The explanation was not good enough of why I can't get the 1TB
