Very bad internet connection

The past month I've had so much problems with internet connections!! Most of the time I DIDN't had connection!! Afrihost did tell me they will credit my account for the week long downtime I've had. I didn't hear anything from them, I contacted them to ask what's going on, and they told me it's been send to the accounts department. With that said, it's not only 7 days now that I've had no internet connection, it's almost in total 2 weeks!!! I have a business ADSL line, and a business to run .... Without internet & email. My personal data on my mobile device has run out and now I'm paying for the data! In other words, I pay for data at Afrihost as well as my service provider for my mobile!!! This is not acceptable and I wouldn't recommend Afrihost at all!!!
