No communication from Tyme Bank

I have deposited a small amount into my savings account with the intention to move it over to an investment account. When I tried to log into my account via browser, I was advised that this service is not available on internet and that I must get the application. I requested a refund of my money into the account where the EFT came from and was asked to send them documents. Since then no communication on the email. Do they not attend to their mail box? I have been struggling for the past week.
