Bad service VODACOM

Vodacom made some upgrade on their towers mid last year in Kuruman. Since then I have poor to none reception where I stay in Kuruman town. I reported this matter with call numbers since September last year. A consultant called me now Saturday 29 January 2022 at 16:20 and said they have to install a booster in my house at my cost of R18 000.00. I told the consultant that I knew that a neighbor received it for free. He said then all he can suggest is that I cancel my contract and go to a different service provider. I am one of your first contract clients and never missed a payment.
