I, SILPI CHATTERJEE, made an advance to Sahara Q shop of Rs. 9800/-- on 14/06/2012.
Receipt No. [protected]. And
F.W.Code / S.A. Code[protected],
At Bhawanipur Sector 1583. Region-- Dakshin Kolkata.
Certificate No[protected].
I was told by Sahara Office that after 06 years, the money can be withdrawn with high amount, that is approx THREE TIMES.
BUT after 07 years money was not returned, and Sahara office gave me a withdrawal Slip mentioning Rs. 28552/-- withdrawn and got my signature on the withdrawal Sli
But money was not refunded to me.
The Sahara office told that money can't be refunded now, the whole amount i.e. Rs. 28552/-- will be kept in Saharayn Universal Multipurpose Society limited. SUPER BB Contribution, for another 03 Three Years. Then after three years Money will be refunded with more high amount.
As per this they asked me to fill up the Form of SUMSL FOR Rs. 28552/-- for three years, and got my signature.
Then after one year i got certificate of SUMSLno[protected] Dated 31.12 2019., Showing only Rs. 9800/--
As Deposite in stead of Rs. 28552/--.
Why this???
Is Sahara India Cheating its Customer???
Make me clear of it as soon as possible.
