I ask carlton for replacement my ab 900 a few weeks ago(i post it here too) and the result they directly sent me AB 2000 instead of AB 900 without my agreement.Now I sent back to them and ask another racket (AS-Ti), and my friend said they might be ask me to pay more about that .Do you guys have any idea about this situation?
Than you so much experts :)
(sorry 'cause before this i post in the wrong site:)

I guess the differnce would be something like 20USD. so might have to pay the difference and i ma very sure they were not able to give you a AB 900 for the simple reason that they stopped production!

I guess u dont lose anything in buying AS ti. A very good racket though!

there may be a chance where they wont charge. You didnt ask for the AB2000 right? They may realize this and may send you the As-Ti for free (the extra charge) because of the mistake
