Bad service

My mobile contract with vodacom ended at the end of October 2013,so I signed up.a new contract with telkom mobile early November.My request was for my cell number to be ported to their network.Up until now that has not been done,resulting in me not been activated onto their network.I had been in their store several times trying to resolve this issue.The sales lady resubmitted my application numerous times but to no avail.Telkom now wants to penalise me for termination of contract and is charging me an amount for the phone.I have emailed their customer care,but there hasn't been a response.They debited my account for the phone without trying to contact me in any way.How am I supposed to resolve this matter if their staff can't help me and nobody responds<br> to my emails?could you please offer some assistance.
