I don't receive any 20% off upto 200 on fashion/beauty etc on my old account

Previously, it was monthly then reduced and appeared 2-3 months gap, then 4-6 months, last received for shoes and beauty in January and April respectively. 

But after that I've not received any. Except 20% off upto 200 on watch is available twice this year, one used in April and the other still available.

This is so wrong that they give this in new accounts but not in older accounts.
