Over promise under deliver new contract

We took out a new device (Cellphone contract) on the 1 March 2019. We asked that they port the number we wanted into the contract. We were told that it was done on the 1st. We unable to receive any calls (Except from telkom to telkom) or sms's and we missing very important calls. I was told to take the device back to Telkom mall of Africa and a sim swap was done on the 3 March 2019. Still no calls or sms's received. The ref i found online as i was not even provided on in store is REF: ********** 2. Now i would like to know, when will this be resolved. Will this ever be resolved? How long does it take to port a number. Can telkom actually port one if they offer to do so?? I was told by your agent that i can return this device after 7 days if I'm unhappy. I will most def do so if this is not resolved by latest 7 March 2019.
