Telkom/Vodacom terrible service

Telkom mobile made the worst decision to join with Vodacom on the roaming service. Vodacom is one of the worst networks in south Africa when it comes to data connectivity, when telkom was with MTN, the service, speeds and connectivity was excellent, ever since they joined Vodacom, the connection drops almost every second hour and you have to go to setting and search for network to get it back on, Can telkom revert to MTN? Vodacom has lost millions of subscribers due to their data connectivity, I ported from Vodacom to telkom for this same reason. Looks like the millions like me who have done that will port to MTN for a better experience, telkom needs to make a choice, either change from Vodacom back to MTN, or lose millions of subscribers to MTN, that is a guarantee of what will happen
