Why is it that AFRIHOST (after selling me LTE product) inform me that I can only use it in one fixed location?

I received my router more than a month after placing the order on 14th of January and could not use it at all since then. I inquired and was eventually yesterday told I don't have connectivity as I use it at a different address than the address on my application. NO where in the application documents did it state that this will be the only address where I can use it. I got other LTE products which I can use at any address and this is the first I hear that I can’t use it at another address. Please correct this or collect the router for full refund. I will have all funds taken from my account reversed if No satisfying resolution is provided by 14H00 today.
