CELLC - CONFLICTING INFO

Due to ongoing issues with the CellC network, I decided to migrate to FNB Connect. This was done at FNB this morning and I was given a sim card to insert after the PORTING was done. I contacted CellC, but speaking to the agents is difficult with 50 people shouting in the background. I was told a while ago that I could cancel at any time due to being a month to month client. I have received various messages - one states my contract will end on 9 December, another states PORTING will be done to my EXISTING number. Each agent has a different story and all I want is for them to CONFIRM that I will KEEP THE SAME NUMBER. According to FNB, this would take a day or 2, but it certainly doesnt look like it. I cannot be without a phone - please contact me with the correct information. Who can resolve this - FNB or CellC!!!!
