Telkom mobile disappointing customer service

I am disappointed and appalled at the lack of care taken by Telkom in taking care of their customers, I've place two orders to upgrade my mobile phone contract which I have received sms's stating that it has been approved, I have not received a phone call from the an agent like the sms stated I would and this upgrade was done almost a month an a half ago. When I did finally receive a call from an agent she stated that she would not be able to help me and I would have to wait for the upgrade Department to contact me. On top of dealing with an upgrade I have placed an other for a new contract and have not received any response regarding this either. Its disappointing to see service like this from a company that I'm am always praising around my family and friends.
