Discovery email change a disgrace !!

After many years of PAYING for our email account , suddenly at the beginning of February we no longer have access to our discoverymail account and to add to the insult my account is debited at a higher cost by MWEB ??. To date still have no access and no notification from Discovery or Mweb. This is neither ethical or right and I will be lodging a formal complaint against both companies regardless of the small amount involved no company has the right to behave this way. We have contacted both discovery and their service provider ( rude and useless) as well as Mweb (clueless). How do you treat customers like this ?
