Vodacom has lost its LTE

I'm paying for and trying to connect to Vodacom LTE in my area where Vodacom claims to have footprint. For almost a week the network is hardly connecting - neither on my WiFi router nor my cell device. I tried for assistance from the Vodacom "Customer Care" centre. Their solution focus on my devices - which I have already tested and reset on a daily basis. Not for a moment did it cross their mind that the Vodacom LTE may have issues at my location. Meanwhile, Vodacom expects payment for their almost non-existent LTE service.
