Repeatedly close queries without resolving the issue

Myself and 3 others in my complex have been experiencing problems whereby we get a strong LTE signal however not able to get a working internet connection. Phone calls and sms work fine. I called the 082 135 call center on 4 occasions with the following results:

1. I tried to log a call, described the issue, gave the 3 other Vodacom numbers get told the call has been logged and then call gets was ended. I never received an sms to give me a reference number.

2. I call 082 135 again to check on the reference number. I get told it was never logged. I repeat all the information again, now I receive a reference number. Later that day I get an sms saying the call has been resolved ("reset alarms on the tower"). I test that same day and the problem remains exactly the same.

3. I call 082 135 again, they need to log a new call. I tell them explicitly to call me before they close the call. I get a call from the Vodacom network department to get more info. Later that day they try to call me again (network dept), but I cant take the call since I am in a meeting. A few minutes later I get an sms saying the issue has been addressed (tower was down but is now back up, please monitor as it takes a few hours to stabilise). I also get another Vodacom sms saying the call has been closed. I test that same evening and the problem remains exactly the same. I tested for two subsequent days and I still do not have any working Vodacom internet connection from my home. When I try to call the network department back on the number they called me a message is played "number does not exist".

4. I call 082 135 again. The consultant states that the call is still pending; apparently if the sms states the call is "closed" it means it is still under investigation, the network department are busy "monitoring". This is clearly not what the SMS's stated ("Please monitor as it does take a few hours to stabilise"). I am advised the network department will call me back.

I am very frustrated that the calls get closed so quickly without confirmation that the problem is resolved. It is very difficult for me to contact them back again and takes about 20 minutes each time to explain the situation to the call center agent on 082 135. A very bad experience, quick to close calls, but do not resolve the actual issue.
