Number Port & bad attitude

Tomorrow 30/04/19 will be the third week I am trying to port my old number back to Cell C, at first I wasn't told I needed an extra sim to make this possible so that was 2 weeks wasted waiting for them to figure that out and not having my business number up and running. Once that was done I called last Tues 23/04/19 & got told 24-48 hours for number port. I called on the 25/04/19 & got told they will escalate the query, 24-48 hours. Call this morning and got told its been resolved but my number has not been ported. Another 24-48 hours. Besides the bad attitude this morning from CellC call centre lady, she tells me it takes 7 business days to port which was never mentioned to me. It took me 3-4 hours to port my number from CellC to FNB a few years ago, I don't understand the holdup!!
