Ekart Logistics — Ekart executives bad behaviour

I bought motorola g62 5g mobile in exchange of my old mobile phone.
Delivery boy came to deliver the new handset.
But as he does not know how to check the valuation of old phone, he simply call said that you new mobile handset will be deliver tomorrow (no efforts made how to calculate valuation)
On further note, I told him to place call with the person who know how to calculate valuation of old phone. Another ekart executive told me that he will visit in another 1.5 hours and exchnage & deliver the new phone. Later he also refused to come and deliver and rudely said he has many works other than this and he will not help in this matter.
So I urge him to contact ekart office, another person from ekart (PEN office) also didnt guarantee that new phone will be delivered or not.
