Poor customer support

Customer services department is dismal. I have had no network on my router for 2 weeks and am getting no help at all from their support system. Having logged numerous tickets for help but the only calls I get from them are when I ask for cancellation. Even on those calls from them they make pledges to sort out my issue asap but nothing comes forth. One of them processed a sim swop for me on the 11th and up to now its still pending for delivery, surprisingly , other agents cannot see the sim swop on their sysetm. Just yesterday their agent told me they'll be sending techs to my place to figure out the problem and assist but lo and behold, no phone call from them and no communication. Appointment was set for 8-9 but nothing happened. To think that i have paid my premium for this month but am having to folk out money for data because the service provider is just not responding is totally ********.
