Privilege card comes complimentary as per their terms and condition and the offer is always there as it is linked to the Priority account.
If someone told you otherwise, either they don't want to help you, or straight lying about it.
As it comes complimentary (paid once the priority status gets removed), you can negotiate for LTF. RM won;t help assuming RM might be the one to tell you that offers comes and goes which is incorrect. So either connect with BM, or find out your corporate RM. If everything fails, get the complimentary card if you want (not a good card now though), do not activate and then negotiate with CC team to convert it to LTF based on relationship or account type or bad reward rate reason.
