I very sad

, Jomsocial! (2.6)unable deleting activities, they maybe fixes in further version, my company don't want buy this product, but finally automatic bill payment, paid.
I wrote and submit ticket, but they don't response

. For example, 14 July 2012 post, answer on 24 July 2012, but after this no sound

.
The site wrote 30-days money back guarantee, but they don't reply e-mail, Facebook and ticket

, and lastly my company not require refund just ask what price of upgrade to Unlimited version? etc..
Anybody know how can I do? I need Jomsocial! answer my questions?
I personally very disappointed of this company staffs attitude and I swear company like that never can gain me 1 cent.
My question is how I can fix if Jomsocial! had bug, after member login and wrote in mainpage, but unable deleting activities, but the button still appear?
