Is this called service?

My message to Tumelo after he said that I could contact him directly regarding ANY issues with my Vodacom signal:<br> <br> Tumelo, you were at my house about 20 days ago to install the 4G booster. That thing only works when I am in a radius of about 5m of it. I have been battling with voice quality in my bedroom now ever since the 4G booster was installed. When I stand next to the booster then I get fantastic signal strength but in my bedroom (12m away) I get 0.75mbps as a download speed and 0.33mbps as an upload speed. <br> Voice quality just goes for a ball of zero. <br> People can't hear me and I can't hear them. <br> Come do something - TOMORROW.<br> <br> This was his response. <br> <br> Please log your call on 082155<br> <br> This after he told me to contact him DIRECTLY at ANYTIME regarding my Vodacom signal strength.<br> <br> What now? <br> Worthless promises? <br> When we had an appointment for the installation of the 4G booster. When I called him the day AFTER our appointment date he told me he thought we had an appointment the following day. I'm an adult and plan my days carefully because I'm a business man. I HAVE TO HAVE a great 4G connection AND great voice quality. <br> <br> I'm VERY disappointed with Vodacom's service and coverage.
