Telkom LTE 24HRS Service unknown users added to my router

For the past year or so we were forced to switch to LTE Internet since telkom told us that they not going to fix our landline cables, we then took the LTE Internet option as we needed connection in March 2019. The connection is absolutely horrible, because every few minutes the connection is down and all devices are connected and it even says connected but there is no internet. Some times we only get internet for a few hours a day and they had told us its better to take the 24hrs option as it will be on everyday all the time, but it isn't and to top it of it's R899pm and we hardly get anything to use. In February 2020 when I had called they said it was down due to loadshedding and the towers are off and this is the reason for no connection at times, then when i called again in March 2020, they made an excuse that it's because people are *****ing the batteries used to keep the tower on during loadshedding, now in April 2020 when I called they said due to high volumes of users during lockdown was their new found excuse. All we get is excuse after excuse after excuse from telkom and doesn't solve the issue, we are paying for few hours of internet when we suppose to enjoy the connection the entire day, everyday....when it rains there is a problem, when it's windy there is a problem, we pay and hear excuses, however if I had to call and tell them I can't pay my bill this month because of a problem they wouldn't care and just disconnect your service so why should be so compliant with their excuses, we paying for a service not excuses. I also noticed that on my software connection page for my router shows current users and the number of users doesn't match the number of devices i connect with the wifi, I then investigated and turned off all devices wifi and noticed there are unknown users still connected to my router, I changed the password and still there it was, still connected....how is this possible. I think telkom has connected unknown users to us paying customers, because I can't account for those devices connected to my router....also it happened just after I had called telkom and the day after there was no internet at all and suddenly it is on with more users, I am not sure if this is what occured because of telkom, but it seems pretty fishy that after my call there are more users on my router which are not from my devices especially after the consultant said it is due to high usage volumes of users. Why should we pay and others enjoy, they should pay for their own internet or telkom should lower their internet prices so more users can pay and have the same service. This is unfair. This needs to be investigated and calling telkom with these issues are useless as they always have some lame excuse and even when you put your point through it is to no avail. For those also using telkom LTE service please check if the amount of users are correct and not gone unnoticed.
