Lodha Group — payment not updated, possession delayed

I made the final payment on 10th of may 2018 for my jodi flat at lodha amara. Two cheques were given at lodha office (Thana) both got cleared on 11th from my bank. I got a call around 15th that one cheque of 2 lakh odd is cleared and the second one of 8 lakh odd is not traceable in system. I was travelling out so have send one of my colleagues to lodha office where he was given confirmation that the payment is received and there was some technical error. I also got the mail for possession some 10 days ago. Now today again one akshita calls me up that the payment is not traceable??? In the past it has happened 3-4 times that the payment was made by the bank and the posting took 7-8 days of time and lodha charged me daily interest for delayed payment even when the cheques were cleared much before the due date. I am surprised at this kind of accounting system where almost every second payment is not traced. If i was charged interest then technically i should be given the interest on the same rate of interest for last 20 days. Moreover still there is no clarity on possession. I got the confirmation of one flat possession, could not understand how will lodha handover half the flat as mine is a jodi flat.
