Cellc roaming flop

Im utterly dismayed,frustrated and disappointed in the service im getting from cellc i have 2 contracts with them. I’ve been complaining since last week bout the network still no assistance, im currently looking for a job and cannot afford the missed call notifications i keep getting. I would rather have them cancel my contracts or port me to another network as this roaming network is not working im Mostly on no service almost all day ruining my chances of getting employment
