Address:

I had booked a 2bhk (B7-36036) on 29/7/2019 in sobha, dreamacres, bangalore deposited rs 1 lakh as first payment and due to bank loan issue, i decided to quit this.
I had done all formalities of cancellation, they told you will get money back within 3 months.
Now it has been more than 4 months, i am following-up with mail and call even reached several time to the office also, they are just telling it is not taken care by this department and making stories.

At the time of booking it was informed that 'sir please make the payment as the price would increase and if you want to cancel just 1-2 percent would be deducted' these were the words of the marketing person who convinced me for payment. For cancellation i went to their head office near sakra hospital bellandur, the concerned person informed that cancellation chargewould be around 8-9 k. I told please process then she told to visit the shobha dream acres office, did the same followed all the cancellation process and the marketing guy informed that they may charge more than 25k for cancellation. I informed him that at the time of booking it was informed that it would be around 1-2 percent than on what basis is it coming so much. He was unable to explain this and informed that he would see and the refund would be done within 3 months. Still no refund.

I need shobha to refund my money after deduction of 1-2 percent as was informed. And if they are taking so much time to refund then i don't think they should even deduct a single rupee as they are using our money in the project.
