No Way to contact Mweb with a quick question and request via email.

I am unable to get hold of Mweb. Holding on to the call centre - I have given up twice, after waiting more than half an hour the first time. I have given up on waiting for an agent online, after waiting for 20 plus minutes. My account was unknown to me, outstanding. I have PAID it, and Mweb has still blocked my account. All I want to do is write an email to say, please reconnect this. You were paid over a week ago. There is nowhere I can write to Mweb, and actually who has hours to wait on a call centre or for an online agent.
