Telkom signal is very poor in my area

I have a Telkom data contract since 2020 and it was treating me good until recently, the signal is very poor when I am at home. I contacted Telkom twice and the consultants told me about the settings, I did what they advised me to do and it did not work and I told them it's not the settings. I am still using the same device I was using and I still live at the same place. They need to check their towers and fix the signal or I am cancelling my contract and I am not the only one who is complaining about the signal in my area they supposed to have picked that up already or they just don't care.
