Peppertap — Unprofessional behaviour

I have ordered groceries and other household needs twice and both the times there has been non-delivery of the products.
First order Id-2382238 date- 16/02/16
on this date in the evening I received a message stating that the shopkeeper has acquired my order and will soon be delivered but the delivery never took place. Then i called the customer care of the company and asked about the delivery of my product. the operator told me that due to some missing products the delivery cannot be done but they portrayed the whole non-delivery as my fault and told that my argument was irrelevant.
Second Order Id-2453803 date-4/3/16
on the above date they delivered the wrong items on my doorstep and I asked them to deliver my products. after waiting for 2 hours i called the delivery boy to enquire about the order so he asked me to reschedule the delivery time which i did. but the delivery has not yet done.
these acts of the co. are very unprofessional and humiliating.
