Lack off customer service

Friday the 24th I did an upgrade on 1my of my mobile contract online and I received an sms later that same day to notify me that the upgrade was successful and someone will be contacting me,the very next day I received the sms again and still no one has contact me in,So intent into the store and there I was told if I wanted the deal on line I should call 10213 or just wait for telkom to call me.BUT NO ONE CALLS.so I called them and after waiting for more then 30min each time other i just get cut off. MY CONTRACT NO IS ********** 604
