No feedback whatsoever! Useless!

Last week one of Telkom's service providers (apparently the company's name is sell direct) calls me to offer me a LTE deal. I took up the offer and was told that I will be sent an SMS with a reference number and that the router will be sent to me via courier within 3-4 business days. Today (three days later) I tried to get hold of someone from Telkom. After being on hold for an hour I was told that I need to contact sell direct. Problem is, I tried calling them and I keep getting cut off. So no one at Telkom knows what to do and sell direct does not pick up their phone. So what to do now? How do you communicate with your customers? Telkom is useless! Their provider sell direct, just as useless! Thanks for nothing!
