Bad cell c service

Shocking service and customer relationship I have had a Fibre media play contract for the last 6 years and I needed to cancel as cell c doesn’t have Fibre in my area and I have been paying R1999 every month and never fell behind . I asked about cancelling the contract and was advised I could port 2 numbers to rain as they have WiFi in my area and the other number I should do a number change so I can convert that number to prepaid I was advised ( after going through the whole company and used up all my minutes …. Nearly !!!!) to do exactly as above and not to rica the SIM cards as they will do it . That same day my contract was cancelled and we can not use the phones at all When I called in they said I cannot speak to Neo directly he has to call me back - well hours later he called me to say no worries I must just get the SIM cards rica’d and he can do the number swop Well it is now the 3rd day my numbers don’t work and when I call them it says my numbers don’t exist I am losing business as I am an estate agent and losing out on sales and my husband and daughter cannot use their phones at all I am disgusted with their service and will not stop until I tell everyone I know not to use cell c at all !!!!! I need a manager to assist and no one can help
