Worst signal/worst service etc.

<p>Ever since i've upgraded from Iphone to Samsung, i've had trouble with the Vodacom signal. Unable to receive emails, whatsapps, go on the internet, view videos, pictures etc. What on earth is going on??? And i'm not the only one complaining, just have a look at all your other complaints on this site. If this issue is not sorted, i will not continue to pay for a contract including data that i can't use because nothing on the phone works, simply because of the lack of connection/signal or whatever the problem is. And yes, i've rebooted/reset/reset to default and everything else the call centre told me to do and nothing works.</p>
