Hello team
i am esha kanda, r/o: gh6/311, prachin apartment, meera bagh, paschim vihar, new delhi-110087.
on[protected] i have booked (leaf design ladies gold-diamond ring) through muthoot fincorp sunder vihar branch, new delhi-110087, and we paid our 2nd emi also but any our personal issue we doesnt want to buy that diamond ring,
so then we goes to muthoot branch they tell me wait for 3rd emi date crossed, then they mail to head office and they give me amount which i paid but nominal penalty they charge and then they give me cheque,
but today they change our words and told me that you pay last emi then we goes to karol bagh branch and sold as a old gold ring, but why we sold as a old ornament, we want cancelled that contract, not a purchase.
kindly resolve this issue asap,
thanks
esha kanda
