Mweb Customer Service SUCKS

Mweb has zero Customer Service - I have been a customer for 10+ years, it suited me to pay annually in advance. Last year I missed my payment for some reason I didn't see the invoice. No one from MWEB bothered to make contact or send a reminder they just cut me off and anyone trying to access my website got a message to say cut due to non payment. I was fuming, I processed payment on 5 January which in my book means my service should run from 5 Jan 208 to 4 Jan 2019. Not so according to Mweb my account is in arrears. as I need to pay according to the invoice date. I have numerous rude mails from Mweb Customer service telling me what their terms and conditions are and how I need to pay according to the invoice date and I am in arrears. I have insisted that my invoice be changed to monthly as I do not have a contract and will cancel my service with Mweb in the new year. I currently pay for domain hosting and am told to keep my email address I need to pay R59-00 per monthly when I question why I need to pay additional to the Domain hosting which includes a email address no one from Customer Service bothers to respond. This totally unacceptable, extremely frustrating and totally unacceptable that any company should treat their customers with such disdain.
