Self-Service Portal Access frustration

I hold an unlimited contract with CellC and for the past 3 weeks I am unable to login to the self-service portal. When I initially took out the contract in Dec 2017 I was provided with a cellc number. After a month I ported my existing number which then de-activated the cellc provided number. I have logged numerous queries to CellC to have them activate my ported number to the self-service portal and have received multiple calls from clueless callcentre agents who do not know how to remediate a simple problem. Without access to the self-service portal I am unable to manage my account and ensure data and voice consumption is within the stipulated limits. Service of this substandard nature is frustrating.
