Pathetic quality of service

Since Friday our internet connection has been the worst I've ever experienced, I get full signal for 2 minutes then no signal for 5 minutes. How does rain expect us to anything online with such a sub-standard connection?? I run an online business that requires us to be online 100% of the day. I'm going to open a case against rain with the ombudsman and ICASA, this is unacceptable. Not even an email acknowledging that they have a problem and they are working on fixing it (e-mails are FREE of charge rain). Some of my clients have churned because of this and I've also missed out on new signups, someone needs to pay and that won't be me. I'm considering opening a lawsuit for loss of revenue, I pay for a service that I expect rendered and well that's not happening, in the process I'm losing income.
