Allow my number to be ported

Good day On the 11th of May 2020 a request was sent by FNB connect to MTN to port my number. MTN sent me a message to confirm that it had received the request and I will be ported to FNB connect in 24 hours. Today on the 18th of May 2020, FNB Connect says it received feedback from MTN that my number was a contract number and should be changed to prepaid. I called MTN and they denied having received the port request and saying nothing changed with my number. Im really tired of being put to pillar to post.
