Poor Afrihost VOIP Service.

I had a VOIP Yealink phone bought from Afrihost with a VOIP subscription for my company. It worked for a while but it suddenly stopped working even though I paid it every month. I contacted Afrihost to enquire why I don't get service anymore and their reply was the number was banned because too many passwords were entered or at least that is what they said Telviva was telling them. Only problem with that was I never entered any passwords as the Yealink phone was setup by Afrihost when I acquired the service. Afrihost provided me with a new password to try but the this did not work either. Everytime they say Telviva whitelist my number but after I enter the password afrihost provide, the phone line gets banned. For Weeks Afrihost told me to do this everytime and it became extremely frustrating to get such poor support service that keeps trying something that don't work. I had to cancel the service as they just refused to fix the problem and I lost more than R3000. My business was also affected by this bad service of Afrihost. I would give a zero rating for their VoiP service if I could. They did not even refund my money for the service they did not provide.
