Agree with Rajkumar Ramachandran, faced similar issues . I bought ticket booking system which has tons of bugs. Don't be surprised to get weird answers for your questions after the payment. After initial discussions I got daily 3 to 4 calls saying the offer is going to end today and you have to make payment ASAP . After payment when I raised the Issues I hardly got response from them. I don't know what 10 years of free support they claim when they cannot give 100 % bug free product forget about optimized because for their developers it is an alien word :)
