I'd say go for British Council . I called up AEO office and the person who picked up the phone couldn't even talk properly in English which put me off so much that I was like no way I"m going for AEO . I decided to go for British council and the procedure was so friendly . Everything is online,just fill up the form ,select the date.You get an E-mail,print it out,go to standard chartered,pay the money and boom u got ur statement of entry ...
As for friendly staff,I had no such hassle with anyone in british Council . The person who took my speaking test was super nice although she was suffering from the cold ,she was a great listener . On the Test day ,reading writing etc that is . The staff was nice,they had a place where u could put ur belongings.Although there is alot of like security,bio-scanning and what not but with the current situation of Pakistan,it is mandatory . What kind of bothered me was that on my test day.My finger print wasn't scanning so they had to make me sit down for like 10-15 mins on the side but it worked afterwards .
