Great Eastern Trading — Delivery issue

Address:

Sinthir more greateastern

We bought water purifier on 15th of Aug 2021, they told us maximum Wednesday it will be delivered, but it haven't came yet, whenever we call them they constantly lie and said it is on the way, at night we call and they informed us it was not coming, im texting you the next day, the time is now 12:44pm, it have not came yet, and the sales person is full of attitude, he is not picking up our phone even, what kind of service is given by them, the store is greateastern sinthir more, we are using many online shopping app, they are so good in their service, it seems that we have made a big mistake as we buoght appliances from Greateastern, we should buy thing on online, after taking full payment why the delivery process will be so delayed?where we have cash on delivery on online?just stp making people foolish, will not suggest any one to buy anything from greateastern, too much bad service
Thanks
