Telkom allows an unauthorised port out of my number to MTN

Good day Telkom,

You allowed my number to be ported to MTN without my consent. What a hopeless company is Telkom Mobile... on Thurs i got this SMS - "Telkom SA: Dear Customer, we received a port out request for this number *****50 number. If you did not request this please reply 'STOP' within 40min of receipt of this SMS. NO RESPONSE within the time limit implies your consent, subject to Telkom release conditions. Please call 081180 for any enquiries" I then immediately SMSed STOP (in less that 5min) as per instruction but that did not STOP Telkom from releasing my number to MTN... now I'm being pushed from pillar to as the call centre staff is not able to help (Both Telkom and MTN) say they can't help me with the port reversal. PLEASE REVERSE THIS PORT I NEVER AUTHORIZED, I GUESS IT WAS INITIATED BY *********. Can someone help me please.... now I was given a number that I was not even aware of. Its people I was calling that noticed that I'm using a new number. Bottom line is that Telkom is a terrible network, how can you release my number when I have indicated that its not me that initiated the port. Please reverse this port out.

My number has now been ported to MTn without my permission? how can anybody request this without me being present? Please re-activate my number.
