Telkom won't allow me to port my number

I tried to port my number from Telkom Mobile (8ta) to Vodacom on Monday 22 June. This should take 24 hours. Till now, 15:47 on Friday 26 June Telkom still has not released my number. I have phoned their call centre, spoken to the supervisor (team leader) but apparently Back Office won't release the number. And Back Office won't respond to the many calls I made. And Back Office can't be contacted by me. Can only be emailed by the call centre.<br> Please could someone get some action from Back Office. They are *******ly holding my number against my request.
