I bought a tshirt amd paid the whole amount and its delivery date was 30th september but till now they have not.. I have callinged their helpline several times but i think they even don't have a customer representative to take the call.. Waited for atleast 15 min, i thought it takes time... They are not picking up the phone.. Such a useless helpline.. Its my humble request to take some necessary step to solve the issue..
