Is it My fault that Afrihost does not have coverage in Jozini. Unfair cancellation cost of R999

I live in a rural area in the KZN Midlands named Jozini, I app**** to Afrihost on the 26th April 2019 for their "Fixed Wireless Special which was 50GB CellC for R349.00 PM, I was ecsatatic, I received delivery of my modem on the 10th May 2019, the same day I left to Durban on business, I set up my modem in Durban and returned to Jozini the Sunday morning, ever since I arrived back in Jozini, the modem never worked at all, I the phoned Afrihost on the Monday or Tuesday to query why I was unable to connect, The consultant I spoke to informed me that Afrihost has no coverage in Jozini and that my best option was to cancel, he did inform me that there would be a cancellation fee, however, due to my situation, I should speak to Finance and ask them to waiver the cancellation fee of R999, which I took his advice, cancelled Afrihost and then contacted Afrihost stating my case, they asked for my address to test if they have coverage, which I did supply as per my application, unfortunately in a rural area, there are no fixed addressess, the address I supp**** was Mapahya Area, Top Town, Jozini, 3969. This is the reply I received from Afrihost: Unfortunately we will not be able to assist if we do not have the address we will need it or the GPS co-ordinates to confirm. i rep**** that I am living in the rural area and that she needed to check their paperwork for the address on the application. Today I receive an email from Afrihost stated as below:-Good Afternoon Charmaine Trust all is well:) Thanks for your response. We have been informed from higher management that you are liable for the cancellation cost. Thank You! Have a great day and please let me know if I can help with anything else! Warm regards Stacey-Lee Afrihost.com Pure Internet Joy! I would like to know, why am I responsible to pay R999 cancellation cost when there is no Afrihost coverage in Jozini, is that my fault? The reason I app**** to Afrihost is because I am desperately in need of the internet, I study online and they had a great offer, when I applioed, I received six (6) emails, asking me to verify my account, now< i just get kicked to the curb and billed R999, for something that is not my fault. WHY?????????
