Casio — Edifice/watch chain damage

Address:

Kolkata, West Bengal, 700017

I purchased a casio edifice watch from pantaloon on 08.12.2015 with a warranty period of two years.within one year the joints of the chain damaged four times.Each time i have to submit the watch at pantaloon for repair and they did it after a week time.After some days the same problem persist again.I have already faced the same problem four times within a year.i request the casio service center to replace the watch chain with a new one to avoid frequent chain damage problem.Each time they just repair it and i have to visit the vendor again and again for repairing purpose.i want a permanent solution to this.please treat the matter urgently as it's a very old case of frequent damage of watch chain.
