All i want is what is due to me

They kept debiting my account for months without informing most times there was no money in my account which ended up in my paying over 200 bank charges for unpaid debits. Whats even more funny is two month ago they promised heaven an earth on how they will deliver my sim card bluh bluh bluh. I am yet to recieve the so-called simcard which means all the money i have been paying since jan should reflect on the sim. I need my sim with all my unused data from last year till current. Richard Branson is running a ******* scheme with the help of his rude staff. I want my phone my 400 i paid for reversed debits n my sim card with data n air time
