Polite and professional customer service to an angry customer

I have app**** to port a Telkom number and other VoIP into MWeb talk. I had been trying to get some information out of MWeb talk as to what was going on. I had been promised return phone calls and correspondence but I had received nothing. I angrily phoned MWeb to get some answers and was eventually put through to Jawwaad. He could hear that I was angry but he did his best to check up on every bit of information on the number porting, at what stage the process was and what I must expect to receive from MWeb once the process is done. He took the time to understand my frustration and politely and professionally helped me. Thank you Jawwaad.
