No service Telkom

App**** for LTE router Aug special for R299. Salesperson assured me we have coverage in our area . Received router plugged in only red light. Was told sim needs to be rika - nearest office 200km away eventyally after 4 days they did rika sim over phone. Still red light next day they told us no coverage in our area. Been trying to get router returned even phoned couriers who delivered router but they need instruction from telkom. End of sept they took dt order for R581 (contract was for R299) today received invoice for R880 due end Oct. Cancellation form was emailed with copy of ID 6 days after receiving router. Received sms stating your case has been resolved but still taking dt order and no courier has collected router. This has been a struggle for 2months dont know what to do anymore. Help!!!
