MTN Are *******!!

Took out a mtn lte contract 2 weeks ago . The sim card works perfectly well in a cellphone , but refuses to work in the router mtn supp**** to me with the contract . I need this data to work from home during this time and cannot keep it in a cellphone. I am paying for the service , but the router does not work. Have been calling and the customer care cannot help , went to a store and they say "sorry we do not know what the issue is and cannot help you" but you will still be charged every month even though the router doesnt work . This is **************** from mtn and utterly disgusting business . Cant wait to move away from this company
