The UK's ISP trade group has contacted Bulldog over an increased number of complaints about its broadband service, The Register has learned.
ISPA contacted Bulldog - the local loop unbundling (LLU) operator owned by telecoms giant Cable & Wireless - a couple of weeks ago to discuss a spike in complaints it had received.
The trade body is due to discuss the issue at an industry meeting today. It expects to contact the broadband provider again shortly concerning the complaints.
It is understood ISPA intends to escalate its concerns to senior management at Bulldog.
A spokesman for ISPA told The Register: "We have noticed a large increase in the number of complaints about Bulldog. We were in touch a couple of weeks ago and we will be in touch again."
He declined to reveal the exact nature of the customer complaints but said they involved "customer service issues".
No one from Bulldog was available for comment at the time of writing.
Last week Bulldog was ticked off by the advertising authority for running misleading radio commercials. ®
