Vodacom business 5g, is it worth it in Gauteng?

I dont have fibre in my area and have been chasing openserve for the better part of 6 years as they have a box on the corner of my road about 500m from my gate yet no movement, zero replies, etc. I have a registered business at my residential address and thus would qualify for vodacom business 5g. Im looking to go for their unrestricted tier, 2TB cap. Should be plenty for my needs and i have seen reports of 250mbps and up but I have been with rain for 2-3 years and nothing but rpain so i am skeptical of ISP claims. My plan is to get outdoor so directional antenna, i am firmly within their "red" (covered) area for km's each way.

My questions focus on speed reliability during peek hours, jitter/quality of their servicing the signal, and experience with near line of sight performance as it would appear my view to the closest tower is slightly obstructed.

Thanks
