Indeed, bulldog have been bought by C&W not long ago, also, they have been going for much longer than since 2004, DSL is relatively new for them, but as a business, they are much much older.

Also, they may be owned by C&W, but they are still a separate business entity. So unfair to put both in the same basket.

Also, moving from one ISP to another is a relatively new process, not long ago you would have had to resign your DSl line with isp 1, then get it installed again by isp 2. Anyone moving at the moment is probably experiencing teething problems as systems and processes are being put in place
