Amazon India — Wrong info on website

Address:

400102

I purchased a speaker yesterday thats the 06 june and they said we will receive it today if i order in the next 8hours. But now they are saying it will take 5days. This is the 3 time it has hapoened with me and amazon is not doing anything.
Also to add to it i had ordered mamy poko pants diapers for my child by the end of may i got a msg stating it will b delivered on 2nd june later i got a msg stating it will b delivered on 5th of june and today is the 7th of june and i still havent received it nor did i got any msg.
When we call the customer service number and speak to someone there at amazon they have no clue about the errors on the website they behave as if its the first time someone has called them about the same. Really bad service, amazon was such good company but now they are behaving like a local grocery store
