Just a question but was the problem resolved??
The csr are a different dept to tec's, but even if they are not directly employed by the company, the company is still responsible for them and their actions...
In this case however the call was cancelled by someone who will always remain anon, so therefore a no show won't count..
You could however complain about poor service and if you do get a friendly csr you might get a deal, eg a month free service, £ 25 pounds off, just depends who you get and with all the flac flying,
plus jobs going if they are any people left there in a good mood...
