Unable to access mycontract website

I signed a new data contract with MTN and registered to access my account on their website. I successfully created a logon ( I know it works as I can use it on the MTN iOS app) but I cannot actually access my details on their website so that I can set up Data Share. I have called their technical support line 1761 (2 Sept) and could not be helped by the support person (told their site might be down and that I should try again later - which I did multiple times unsuccessfully). I emailed customer care on the 9th and received a response on the 10th by Simphiwe Twala where he referred me to the Business solution supervisor (Ref No: ***2). I have not had any response since then despite sending another email on the 20th of September. I find it ludicrous that a telecommunications company cannot communicate or sort out technical aspects efficiently.
