MWEB's INCOMPETENCE

I took a LTE 50GB account with MWEB ISP the package was activated on 02 July 2019 and I wasn't furnished with my account login details to view my account online, including usage. 3 days later I received an email that I had used up 50% of my allocation and I couldn't access my account to view this. I have been communicating with them endlessly, they are always telling me they are working on it but I am receiving no further assistance. I believe they know what is causing this problem, however they are continuing to leave me in the dark. This is not honouring the contract on their part and I feel like I'm being taken for a ride so that they can bill me outrageously.
