how does mdu works? because i have heard that sometimes when a dtv cust wanna move and will be moving to a mdu building, they have a lot of problems with them, no option to process the movers order, to convert from a regular account to a mdu account and all that. how mdu really works? what can be done? can a regular customer change to mdu and viceversa? can a regular customer move to a mdu building?
