LTE Router is faulty and Telkom won't replace it

I was forced to move from ADSL to LTE. Got a new DLink DWR956M router which on the 3rd day it got activated It threw off my settings and took out my wifi name and password, it moved back to factory. I left it at that, called telkom the lady tried to talk me through the settings again, everytime I plugged in the Lan cable it kicked out the internet signal. The lady told me leave it on default. As of yesterday no internet light, it's not green or blue or red. Its just now coming on. I took it to Telkom Bluff, the gentleman told me he can't give me a loan router, I have to wait 2 weeks to hear back. Dlink themselves told me they are having issues with this router, furthermore I received it on the 3rd of October, got it Activated on the 6th and it kept pushing my settings out. I'm a student and can't afford this downtime. I'm a distant learner, Telkom is making me life miserable as I'm in the middle of exams!!!
