Appalling and pathetic service

I've been going to Telkom mobile , to take out a cellphone contract 2months ago. I went to Westgate , for one whole month, where the service was appalling an pathetic and couldn't assist me. I then go fed up and went to the Clearwater branch, where I thought I would get better service. They managed to assist me , whilst having a power outage, so I thought well done to them, they are changing my perspective of how they operate. That they were willing to go the extra mile. Anyhow after a few interactions of sending the relevant documentation, the contract was approved. Its now been a month since I heard from them, I send sms's, emails and even call the landline, where they do even respond to me, as apparently country wide they don't have stock of the huawei p8. But month after month they coming out with specials for this phone. When I went to the shop physically, to find out whats going on , they not sure. There service is disgusting to say the least, but they want to have customers on their books. I'm still waiting patiently for this lack luster company and its employees to call me and keep me in the loop hole.
