Porting to another ISP

After being with Telkom for so many years and overlooking so much mistakes, ive finally had it, i tried recharging airtime via the Capitec app and the airtime wont relect R150 worth of airtime this being the second time its happening in one month im really porting over to another ISP. When you call telkom mobile you wait for over an hour to end up not getting through to an agent
