Flipkart — Not updating my phone number

I have been requesting flipkart customer care guys to update my phone number as I don't have access to the present number the account is linked to. I have raised this request 10 days back but nobody is working upon it. The worst part is they have deleted the previous number from my account and I have been logged out from the account post that and I can no longer login to my account and can request for call back. The toll free numbers available is not allowing me to talk to any customer care executive. There is no follow ups happened till now if my issue has been resolved or not. So careless to even follow up to check if the customer complaint has been resolved. I have forwarded my id proofs also to [protected]@flipkart.com multiple times but every time they will ask me to send it again. I feel blocked and helpless now. I personally feel they have pathetic customer care services and they are quite rude also. It is much better to switch back to Amazon as I have very pleasant shopping experience over there.
