Pathetic All Round Customer Service

I am very disappointed in the customer service I received from Afrihost via WhatsApp, Email and telephonically. I signed up for the Pure LTE MTN , after specifically checking with someone from the support team on WhatsApp Chat that the router I was getting - the Huawei B535 would be compatible as I did not see it listed as one of the devices on the website. So I received the SIM card today, popped it into the router and set it up, and it worked for 10 minutes before the light went red and there was no service. I called and sent a WhatsApp, only to be notified that the sim had been deactivated because I am not using a compatible device, and it won’t reactivate till I acquire a compatible router. I sent through screenshots of the confirmation as requested by the consultant I spoke to telephonically, and I have not received any resolution or way forward. A consultant on WhatsApp told me that I must cancel the service, it’s all I can do, and it will cease at month end, but why must I now pay for a service till then that I cannot use. I understand and accept that mistakes happen, but I do not accept the way Afrihost has handled this. This is extremely poor customer service, basically all I am getting from all angles is that there is nothing we can do from our side, you can cancel or sort out a new router. No admission that the mistake was made on their part, no apology or attempt to offer an alternate solution. I guess it’s just one more small customer to them. No great loss. I honestly expected more from Afrihost, my mistake I guess, and other than not using them personally ever again, I will not recommend them to anyone else.
