Shocking Service!

I went to the Telkom ballito store about 3 weeks ago to apply for an LTE contract and was informed that I will get feedback within 3 business days, it has been 3 weeks and nothing. I've been trying to call the call centre sales dept. to follow up and for the past week nobody, not one single person has been answering the phone, I've been put on hold for periods of 20 to 30min until I eventually give up. What kind of a business runs like this? I took my time out to go to the store, surely it is only courtesy to get back to someone whether positive or negative. There's so much bad publicity around Telkom and you would think that such a big organisation would at least work on providing excellent customer service to change this...surely you can't run a business like this!
