Jika Mobile is a ****

Good Morning. Jika Mobile sells data contracts they insist that the SIM card works in your area but it doesn't. You end up buying a router R1000 and the data contract is R349 and you cannot use it as this sim card doesn't work anywhere! It's been 2 months and Jika mobile is still debiting me and I cannot use the SIM. This business is a ****. Hello Peter, Please can you assist.thank you. Pagan Cooke-Tonnesen
