Vodacom 4G not ringing

Vodacom did contact me on the 29th but the consultant was still not clued up with what could be wrong and escalated the issue( Ref:S4-36121-196ps) since I’ve been calling customer care every second day with a hope to get someone who knows the issue but it’s a hit and miss, last week I spoke to one consultant by the name of Happy who said Volte won’t work if roaming is active & she disabled Vodafone World successfully but missed the part to re-provision VoLTE on my sim & the problem persisted, on 29th in the afternoons after going through google & saw other customers complaining & confirmation the culprit being roaming I knew I’m one step closer since it’s been disabled on mine, I called customer care to enable VoLTE which she struggled to understand & i said please activate LTE services on my number & after few confirmation sms that LTE services are activated & VoLTE services my problem was solved, I’m now able to make & receive calls while my signal is on 4G, it had to take complains on various columns to see what could be wrong but from Vodacom side there’s no one who was able to see what’s wrong & it’s so difficult to get through customer care instead you are offered Tobii so you choose whichever option to try and speak to a person, I’ve sorted problem myself Vodacom consultants this is still a grey area maybe it’s because it’s a rare problem it affects 2 in 1000.
