Redbus — Full cashback not received

I have booked 2 tickets from Indore to Khandwa on 17th oct 2016 and used the code CBOCT and it said that Rs114 cashback u will receive but i had received only 68. I had called to customer support there they always tells that you will get the remaining cashback in 24 hours but still not got. Its been 11 days and not received remaining cashback. So tell me that when you are going to send me te cashback. Tell me that also whether you are going to send the remaining cashback or not.
