Lodha Group — crn and welcome email not received

I have given 2lakh as token amount for lodha casa royale grande - thane on 10th may 2018 and as per communication received from sales team crn supposed to be generated and welcome email to be received by 17th may. Not received anything till date. I also spoke with back end team and they told me they haven’t received any file from sales team. As per terms n conditions next payment is due in 2nd week of jun. When i spoke with sales team they told me they have released file to back end team and back end team is saying they haven’t received anything. They are giving me assurance that i will get my crn asap but it’s taking too much time. I request to generate my crn n send me welcome email asap.
