Shockingly bad customer service and not receiving my order and its now 2 months down the line

I ordered my SIM card nearly 2 months ago and it still hasn't been delivered, and I have not received my order. I have phoned and sent numerous emails and the customer service is worse than pathetic. They keep telling me that the order is on its way to me and I can check my tracking number to see where it is. They didn't even bother to check this themselves. On checking the tracking number their courier didn't deliver without a reason except for exception and hasn't bothered to try deliver again since 11th February. The courier company has never even bothered to contact me at all. On sending yet another email to them to tell them to look at the tracking details themselves so they can see that the order is not on its way, I was told that this would be escalated and they would give me feedback. Another week down the line and I did not receive any feedback, contact, or my order. I sent yet another email asking for a manager to call me or to cancel my order which took them a week and a half to reply to. The reply - they are waiting for feedback from their warehouse. I have sent yet another message asking for a manager to call me or to cancel the order. This is being ignored yet again! Shame on you Afrihost! Get a manager to call me or cancel my order - this is absolutely unacceptable and non existent service!!!!
