Mondelez India Foods / Cadbury India — Celebration pack of cadbury

I had complained to mondelez and also registered a complaint regarding the bad appearance as well as taste of the cadbury chocolates in a particular cadbury celebration pack(purchased from a local shop of chatrapur, odisha) with a reference no. of-Ref # S[protected] and they said they will visit my place within a span of 7 days but nothing such has happened and its been a month since registering my complaint.The chocolates had blister like appearances on them and tasted awful when i said this to them they said to keep the whole packet and i am having it with me for almost a month(from 23rd sept) and ants have destroyed some part of it for which i called them again and even sent a photo of the same but no steps have yet been taken from their side.These all might cause ill effect to the health for which i informed the company to test their product but this negligence from their side is totally unexpected.Very dissatisfied with their service...
