Poor service

I received an online LTE router a while ago and have been experiencing issues with network connection for a month now. I took it in to a Telkom branch and was assisted by the support staff who changed confuguration settings, etc. I still received the same error and took it back to the same support staff, he then checked the coverage and advised that I am having issues due to the fact that there is no coverage in my area, as a result, I should not have been given the router to begin with. In between all of this, I logged a case (Case no: ***4) on the 19th of July, it is the 1st of Aug today and I am being sent from pillar to post with no resolution to my issue. I was advised that the turnaround time for cases is 72 hrs and its been 2 weeks waiting for feedback/assistance with a cancellation!!
