I had order a product with order id od[protected] nokia mobile phone but i don’t like that because of poor camera quality and it have slow screen response problem, but my account was blocked due to which i was not able to process the request as i got message that due to high number of returns you are not able to process the return request and because of that my id is blocked. Repeatedly i am reverting on every mail and calling daily to customer service but till now no solution is given.
I know system had detected high number of returns because before few months i ordered some cloths but find some size issue i wanted replacement for that but size was not available and seller offered only return /refund to me because of that i had returned some of products and i called customer support for that also but they advised me that if i purchase anything then i should purchase 2-3 items of same product with different size so that i can keep product which will suit to me and rest i can return and because of this i ordered so many cloth and shoe and in which i returned most items which was not suitable/ and was not fitting to me otherwise i never had done like this i dnt know because of this system is detecting returns but before this no any intimation mail or letter was given to me so that i became aware to this but sir i request you to help me in unblocking my account and help me in returning the product i was not aware of this flipkart had not given me any warning before blocking my account, please i need my account to be activated. I had also mailed documents which flipkart wanted but no resolution is given please help me sir because its all about my 14000/- rs which i want refund please help me in this because customer support is again and again giving same reply that my account will remain block and i will not be able to process the return. I don’t want fake assurance but i want clarification for this so that i can take further action accordingly
