Bad service with accessing my account, no assistance at all

I took a contract with Telkom just before lockdown was announced, registered my profile on their site, downloaded their app on my phone. I did this so that I can top up my data via Telkom app or site. Its been a month now that I can not login to my account. When I login to the site, it redirects me to the home page, when I use that App, it gives me an error that they can not retrieve my info..strange enough that I can monitor my usage on the app even though I can not access my account to top up. My main issue with this is that it affects me financially, being unable to access the site or app means I have to top up using my bank app and that is very expensive. On the bank I spend R149 for 2 gig whereas if I was able to access Telkom's site I could spend the same amount on 20gig. I called the call centre and spoke to a lady by the name Zimasa who advised that I should send her an email with the error message I get on the app, till today she has not contacted me. I am running out of data and can not be spending so much money again.
