So whose to blame?

<p>I am really in a predicament. A couple of months ago we started using Afrihost as an ISP. My husband then moved his cellphone contract from Vadacom to MTN through Afrihost as the service provider, and the process were smooth without hickups. I decided to also move and last Friday 2 December my number ********** 447 transferred from Vodacom to MTN through Afrihost, and the process derailed. Some people (like my husband) can call me, but others like my mother and sister can never get through to my number. We even attempted to call from the same location (my parent's house) with the same result. My husband get through, but my mother not. The missed calls do not even show as missed calls on my cellphone.It seems like MTN numbers get through, but not Vodacom numbers (although I can not say with cer*****y). However I can call any number and get through. The problem is that Vodacom claims that the issue is with MTN, and both MTN and Afrihost claims that Vodacom is the problem. The end result is that no-one is prepared to accept responsibility and fix the problem. As the consumer, I am now paying for a bad service experience and I am not even certain how many calls I am simply losing. I look like I do not care and do not respond to missed calls. What can I do?</p>
