Should have stayed with Cell C

I had a contract with Vodacom since 1998. I went to Cell C in 2019 because Vodacom service was poor. After my two year contract with Cell C I decided to go back to Vodacom just because cell C signal was bad in our area. Their service was world class. I went to a Vodacom store on Monday. They said they need to port my number, and that they will phone me the next morning to finalize the contract. The next afternoon I went in to ask them, because I did not have reception for a day. No excuse, they just started to do the contract. Needless to say, I signed everything, was told everything was okay. Tomorrow it will be four days with out reception. The Vodacom shop said everything on their side is perfect...they will escalate it and it will take 48 hours. I am working from home....do they think it is okay if you can not be contacted in 5 days??
