USELESS CALL CENTRE - BAD NETWORK

My problem:<br> I have an android phone running android 5.1.1 (Samsung Galaxy Core Prime G361H) it fully supports the frequencies of all the networks in SA. Whenever its on HSPA, there's no internet access, I can't send/receive SMS's or send/receive phone calls. However when it is on HSPA+, or in rare cases, on normal 3G, it has full access to the internet, I can receive/make phone calls and receive/send SMS's.<br> Why I am angry:<br> I phoned 180 twice. the automatic response was, \Please check the number and dial again.\" On my third attempt, there was an answer and I eventually got through to the call centre. A lady answered and asked how she can help. I explained the problem, but it was obviously above her pay grade since she told me that there was nothing she could do about it. She then asked me for my address to look up the coverage. She then told me that there was no coverage here whatsoever, I find this hard to believe since I was in the area she was talking about, talking to her over the very same network. She then asked about my problem again,I re-explained. She told me she was putting me on hold and then immediately ended the call. (I used 2G to make the call, there's full coverage)"
