Online shopping issues with Dis-Chem

I have realised that a lot of companies seem great until you place an online order with them. I placed my 3rd online order with Dis-chem on Friday using my online account but now I can’t even track or get an update on it because the very same account says “account couldn't be created due to information mismatch” when I try to log into it. Tried calling and sending emails to the support team but they don't seem to be bothered.
