No response - Without email for 54 hours now

I've logged a call with MWeb Business that I cannot receive any emails 54 hours ago. Up to now I made an additional 5 calls to Mweb Business, emailed about 4 times and the only reply they can give me is that I must let the senders know to activate authentication....so do I let everybody in the world who might email me know this? There is something wrong and I really get BAD service from Mweb Business. <br> <br> The so-called technical center tells me that this issue is this and that department and no one is taking ownership of this issue. Not sure why I write this, as MWeb Business just does not phone you back.<br> <br> This is the second time the same issue occurs - the previous time I waited 5 days....I loose business and I cannot wait this long....<br> <br> If I may - please make use of other service providers as Mweb Business just does not care about you.
