Unable to make calls or send sms's

<p>I ended my contract with Vodacom due to what I considered as invalid billing. </p> <p>However , one month later (since 1 december ) , I am unable to make calls or send sms's from my cell phone. </p> <p>As an apology , Vodacom sent me 1gig of data (which i could not use due to the fact that my mobile data stoppped working as well) .</p> <p>This is apart from the airtime that I have lost after topping up , due to the fact that I have been unable to use it because of the non-delivery of service. </p> <p>I have called your call centre approximately 8 times this month . </p> <p>Each call centre agent promises to log a call (not providing me with a reference number telephonically) , with a promise that a reference number will be sms'd to me. This has never happened . </p> <p> </p> <p>Please can some one competent contact me to handle my issue . </p> <p> </p>
