MTN service still sucks

A new data device was delivered to me BUT with no SIM card. MTN swear blind that it is impossible for that to happen, and I MUST PAY FOR THE SERVICE. I haven't had access to the service, so why must I pay? In the meantime, there has been no resolution to this issue, and my cell phone has been suspended TWICE. I am still suspended, As a pensioner, how do I get help if something was to happen to me??
