Terrible service / Charging without delivering

At the start of Feb 2018 signed up for a Rain LTE package from Afrihost. The order included a HUAWEI modem for use with the LTE service. I got charged R999 to my credit card. After a couple of days I asked when my device will arrive. Afrihost confirmed it to be with the courier company. A few days later I asked again and got the response that the courier company will call me and as a result of a error on my profile there was no order number. The day there after I am informed that the device is on back order. I ask how long this will take as I currently do not have any home internet and need the fastest solution. Also proposing just delivering the sim in the interim. I sent several emails asking questions getting no answers. I cancelled my initial order - and ordered a sim only package - which at this stage came with 3 months fee access. 16 Feb I get a email telling me that my package is en route. By the 22nd of Feb - Afrihost had not delivered and I got a email from quality assurance how my recent interaction was with Afrihost. I fully detailed the process and complained about the poor service received and asked that somebody give me a phone call to resolve the problem. No one called. By this time delivery was also arranged for specified times and delivery never happened. By the end of the month, the SIM ONLY was eventually delivered. I received a email reply from quality control to apologise for the poor service and also indicating that I have not used the device. By this time I already had Telkom ADSL installed. I ordered Telkom after Afrihost. To date I have never activated the device. I cancel at the end of April - (within my 3 months free service for SIM only packages) - I get a bill for May for R549 - and I am further hit with a cancellation charge of R999 - for cancelling. All of these charges to my credit card - so I can't stop the charges. That is R2547 - I have never received a router, was in my free months, never activated the product. This is absurd. I have sent emails to support and accounts on the following days: 2 May, 7 May, 8 May and today on the 11th of May. No one has come back to me. This is in the top 10 worst service experiences I have ever had.
