funny how nodody recognises Dhani

We are in the uk and been following the programme with great intrest. What we find unacceptable is how come Taima does not recognise dhani from the time she threw her out of the doli and pulled all the jewellery. Also madhu's mother-in-law went to Amber's wedding still did not recognise her when dhani went to their house when some function was taking place. Are we also saying that no-one in the family even saw dhani's photo. I am sure the creatives should have thought of this before trying to fool us.
