No contract, ONE HUGE CATCH!! Please avoid them!!

I signed up for an Afrihost LTE package in middle December 2018 with the SIM ONLY option, since I have my own router. They advertise that it is a month to month contract and that you can cancel at any time. In their own words: No contract, no catch. HOWEVER when my sevice in Seapoint was absolutely POOR, I cancelled my contract in February 2019. Then I received an invoice from them, stating that I need to pay them R999 in cancellation fees. I immediately contacted them, and a consultant rep**** that it is because they have to recover the LTE router that they gave me. I did NOT take the router option as I have my own. I rep**** and then the consultant changed his story. Now suddenly it is because of the promotional data that I received in December. Funny thing, the month to month contract is for R219 a month. But they want to charge me R999 for one month’s promotional data. And I only signed up in middle December, not even using it for the whole month. Them they were quick to state that if you CANCEL WITHIN 6 MONTHS, you have to pay cancellation fees! This is absolutely FALSE ADVERTISING, since they advertised it for a month to month basis and a person can cancel at any time! PLEASE DON’T SiGN UP FOR THEIR POOR SERVICE AND FALSE ADVERTISING!!!
