I don’t know if it’s bad service or what

Hello I’m very much frustrated as im writing this I bought a data sim card from MRP mobile. So I told them I would like to use my vodacom number they said it’s not a problem they will ask vodacom to port number when I got the sim card I immediately let them know I want to cancel I don’t want to use the sim anymore they said they will let vodacom know to reverse action this was last week Wednesday, on Saturday 8/12/2018 it was still not working I went to Ilanga Mall vodacom shop they consultant told me they needed to approve it it will work within 24 hours on Monday 10/12/2018 I called again spoke to someone she said the number have to be activated it will work within 72 hours. Today I put the sim card in it’s till not working. I called again spoke to a lady she said it will work within 72 hours again. I have been a loyal customer to vodacom this is unacceptable. The number in question is ********** 640. Do I have have to change my number I can’t deal with this back and fort I use this number for business it’s frustrating ?? Please advice urgently ? you can get me on number ********** 923 Thank you
