Unresolved matter

Compliments of the new year to the Hellopeter family.For almost ten months now,i have been experiencing loss of signal and unable to access a full use of my cell number(some days i can not even make calls,other days i can not make nor receive calls and messages).Sad reality is my contact number is linked to a whole lot of things..Work OTPs,Banking OTPs,Personal accounts including as my contact number for both private and work related matters.I started using my contact number early in the year 2002 using MTN pay as you go and then only seven years ago in 2016 i had to Port my number to Telkom since the price of data was more affordable with them.For the past 10months i have written emails and even Physically visited Wonderboom and Wonderpark Telkom stores to find out what was the couse of my challenges,to date there is no proper feedback ,i only receive automated response saying the matter will be attended to by a technitian.My concern is when i recharge with a telkom voucher the voucher is accepted then immediatly i try to make a call i will be told in most cases when i do not have sufficient funds.I permanently receive a pop up reminder stating when my sim card was unable to be detected. My emails were dated as such: 1. 11/11/2023 18h02 2. 14/11/2023 23h39 3. 29/12/2023 12h51
