Failure to porting from fnb connect network

I am very angry at fnb connect for their poorer network. I thought the network was cool then I joined it but after joining it I realise that I can't even hear properly the voice of a person calling me and bought a lot of data for internet but I can't even use that data, internet doesn't even begin to load it just keeps failing time and time again. I've been sending porting request for the past 4 days but they are not approving my request. I think fnb connect is doing a **************** with their network. I want to go to telkom mobile but fnb connect is ignoring all my requests . I can't lose my number.
