IP Address blocked, NO RESPONSE FROM SERVICE PROVIDER

Webafrica blocked my IP address on my work laptop, which means that I am unable to send and receive any emails. This has been 2 weeks ago. I logged a ticket to address the issue with them and since then I have received no response, no help, no call, no message, nothing! I have been unable to do any work for 2 weeks now, I have never received poor service like this in my entire life. Will have to cancel our subscription with them as it seems that this is their standard way of dealing with paying clients. Shame on you webafrica!
