I am highly discussed with Vodacom cellular provider's service

I am highly discussed with Vodacom cellular provider's service. I have numerous time reported signals/connectivity problems in my area. This has been on and off for the last year. I have my own business and am unable to run my business successfully due to clients's being unable to get hold of me. In the meantime, I am paying a monthly contract fee for services that I can not use. My last complaint was closed with no resolution. Please, please, please...stay as far away as possible from Vodacom. Seems like they are a bunch of useless amateurs unable to keep connectivity going. Sound more like Eskom every day. From a very disappointed 25-year long client of Vodacom....or should I rather say Vodauseless.
