Sales Calls and Wrong Numbers

Just had a call, on my land line, from a company called Summit asking if I wanted my guttering and fascias done. I pointed out that this is a low rise council block so the council deal with that. Telesales person was not happy about this.

I then noticed that I had 11 messages on my answering machine so I listened to them. Four were automated sales calls, 2 were hang ups and the rest were all wrong numbers. Worryingly one wrong number was a GP's surgery trying to set up an appointment, one was a school wanting a parent to come in and talk about Karen's progress and two were Kingsheath job centre reminding Mrs Kaur that she had an appointment with them last Tuesday.

This phone number has been registered with TPS for nearly 2 years now.

As they called me on my landline I didn't get their number on my phone and when I dialled 1471 I got a message that they had withheld their number any how.  I did some Google searching and the only number I could find is their 0800 sales line.  I think their address is:

Summit Cladding
Summit House
Loughton
Essex
IG10 4DX

Although there is a company in Birmingham called Summit Roofguard at:

21 Sovereign Road
Kings Norton Business Centre
Birmingham, B30 3HN  

But as the person who called me only identified the company as Summit I can't be sure which of these it was if it was either.
