Unresponsive & no service!

I want to get internet at home and decided the LTE deals from Web Africa would work for me. I ordered it and paid a pro rated rate for the last week of November. The end of the month came and I then was debited for the month. I have yet to receive an internet connection from them. I am not sure if it's the router or the sim card that's faulty. I called and after 40 mins of being on hold for the 4th time I got through... A guy from Tech support was trying to help me but halfway I ran out of airtime and the line died. He had my number and I expected to hear back from him but he didn't call back to continue helping me! I tried calling back the next day and just couldn't get through on the line. I have sent SEVERAL emails and no one has gotten back to me. I am very unsatisfied and angry. It might be a simple fix, heck it might even be my fault but I wouldn't know. 3 weeks with this and a few hundreds wasted. The deal is not with the admin!
