Poor service delivery and bad attitude from consultant (Nomlpumelelo)

I bought a fixed wireless router from Afrihost 2 weeks back. The device was delivered last week Monday. I have been phoning afrihost everyday since i got the device as it is not connecting to the internet. All the consultants I have spoken to keep saying they will escalate the matter. It has been a week and still the router is not working and Afrihost has not bothered to contact me. I call them today to ask what the progress is, I speak to one of their consultants (Nompumelelo) who was extremely rude. She tells me the area I stay in has no network coverage. This is strange as none of the other consultants has mentioned this. I explain to her that my address was checked for network coverage before I signed up for the package. I also ask how none of the other consultants has picked this up, she then says to me it is because one of the other consultants know how to check the network coverage (Afrihost how do you employ technical call centre agents that do not know how to do their job?). As if that was not enough Nompumelelo decides to drop my call. I am beyond annoyed by the bad service and Nompumelelo's attitude annoys me further. A few minutes later I call afrihost and ask to speak to a supervisor who then confirms that I have network coverage. I am hoping that this supervisor will actually follow up and sort this issue out.
