Ported number not working properly on new Mr price sim card

I recently ported my number to the new Mr price sim card. The number did port but I can only receive calls. I can't make call or use data or load airtime or data. Everytime I want to check the balance using *140# is says "MSISDN is not linked to ussd". It's been 2 days. I called customer care stay on the line for 12 minutes long no one pick up. I am so furious and I regret porting my number to Mr price mobile. Can Mr price just please link my number to the ussd and activate my ported number with the Mr price data services.
