Can't complain about customer service because it seems to not exist

I have been battling with connection problems for more than a month. My line keeps dropping. Open view tested it, my equipment is in order as far as they are concerned, and simply closed the complaint. Mweb has been advised on several occasions now it's not resolved. The line drops on the box installed for fiber access by Open serve. It seems MWEB doesn't care about customer service anymore for they do simply not respond to resolve the matter.
