LTE-A service unusable for 2 weeks now and Afrihost not fixing it!

For the past two weeks LTE-A is unusable, I have logged numerous support calls. Fist they wanted me to troubleshoot my router which wasn't the problem. Then they acknowledged the problem was with the RAIN network and said it was fixed...it wasn't. Then I noticed the MyBroadband forum littered with posts of many people complaining about the same service. Then Afrihost started sending us a link to complete to complain about the service which gets sent to RAIN. Then the form stopped working and I had to furnish details of the router manually for them to submit it to RAIN. Its now become totally unacceptable. I am paying for a service that doesn't work. I want a credit until the service is sorted out. I have signal, I am in the coverage area and its worked fine until now. Afrihost is hiding the issue and not coming to its customers to say hey guys, there is an issue, were working on it and we won't charge you until we give you what you pay for. I will stop my debit order if they don't confirm a credit for the past 2 weeks and until its fixed. Afrihost please respond!!!
