bad bad bad service

I am so disappointing in the service we got from Telkom Mobil this past month, I app**** for a new device from menleyn mall store the on at fruit and verge, after not hearing for a week from them and tried to find out what is going on from the call centre for a week I drive to the shop again 50km just to here thy never summited the transaction to Telkom then lady very helpful assisted me and summited the transaction then I wanted to upgrade my other contract and she told me the system is now blocking my upgrade as well because of the other device contacted being pending , so went home again after wasting 100km and 2 hours of my day . can someone please just get back to me and tell me can I now upgrade and what is going on with the new device I never had this problem with my other service provider
