Informed plusnet that I'm moving to talktalk who have just llu'ed my exchange because I want to take advantage of the greater speeds I can get on LLU and talktalk are the only provider who offer this on my exchange.
Here is the text I got this morning from Plusnet verbatim:
"thankyou for your enquiry in regards to the speeds we will be able to give you the same speeds as what talktalk can provide this is because we all run on the same wires although it is a different provider if you would like to upgrade your speeds please contact our technical team"
Apologies - Plusnet got in touch and asked me why I was leaving to which I replied this:
The only reason I am leaving is because TalkTalk have just LLU`ed my exchange so I can now get a much faster speed. I have had no problems at all with plusnet and will certainly be happy to rejoin if and when Plusnet LLU is available on my exchange. "
This was the message I sent that preceeded the text I recieved this morning.
