Simcard still blocked

<p>I cancelled my contract with the One2One department more than a month ago. It's been more than 2 weeks that I can not use my cellphone number. I called their department and I gave them the pin at the back at the simcard but eversince its still blocked. The staff at the One2One department is *********** to do their job. I dont receive bank notifications. This is utterly disgusted. </p>
