Poor service and bad attitude

I have been a Mweb customer for about 20 years (dial up days). I use an uncapped adsl service. For a period of about 5 days in July a large amount of data was downloaded at which point Mweb decided to throttle my service. My monthly usage is normally between 50 and 90 gigs but in July it was 139 Gigs. for the first 6 days of August I have used 9 Gigs. Every morning I get an email to say I have misbehaved and therefore been throttled. I battle to understand why they sell a product as uncapped when in reality they cap it. I am being seriously hampered in running my business and today phoned Mweb to be told tough luck as there is nothing they can do as my usage is to high. I pointed out that since 26 July I am averaging about 1Gig a day, but this is still too high.<br> This is unacceptable service for a very long standing customer.
