Very poor service from Vodacom

Opened a 4th contract at Vodacom for a home LTE system on the 27th of January. Since the beginning the Sim card showed an error "network registration failed". Visited vodacom in Worcester did a network sync, sim swap and a service request done still the new sim gives the same error. Vodacom customer care was phoned 4 times with no help. Apparently it is a "back office" issue and clients can not be put through to them. The payment off course has gone through without a problem on the 1st of February but No service from their side.
