Hi Mags
Thanks for your email. So I presume you want to change from Orange because they have asian call centres am I right? There are many broadband companies with UK based call centres including BT Broadband.
Having an asian call centre does not necessarily mean poor customer servivce. I would always look at the overall customer service history of a broadband provider (such as in our customer reviews) over where their call centre comes from.
Also some of the worst call centres are based in the UK, so service is not geographically linked.
If you want to play it safe then BT Broadband would make sense, the other alternative is to go small - most small ISP's don't need to outsource their phone support so they keep it fairly in-house with a few people.
People like Madasafish, Direct Save Telecom and Eclipse Internet have friendly staff who will respond to your needs in a timely and effective manner.
Cheers
Jason
