I understand it can be an area of concern, dispute and litigation. But, my personal views for shared facts are as follows:
A. Providing Advertising services in a Cinema-Hall are NOT directly in relation to an immovable property in my humble view. This is subject to my presumption that the subject ads are NOT directly concerned with any immovable property of your client For example, If concerned Ads are for selling project/s by a builder-client, then, such ads will be directly in relation to the immovable property/ies. But if these ads for selling a ''goods" manufactured by your client, then, these ads are directly in relation to those "goods".
B. If you notice Section 12 (14) of the IGST Act, 2017, it specifically deals with 'advertisement services provided by way of dissemination in the respective States or Union territories as may be'. However, this clause is applicable only when service-recipient is 'the Central Government, a State Government, a statutory body or a local authority meant for the States or Union territories'.
C. In my view, Display of these advertisement in a Cinema-Hall is more akin to services linked with 'Place of Performance'. And Section 12 (4) does not cover 'Advertisement Services'.
D. Lastly (& most importantly) and assuming that said service-provider is wrong at his end in treating place of supply as 'Haryana' (instead of say 'Punjab'), I do not think that that is a relevant factor to legally deny ITC to your client.
All above are strictly personal views of mine and the same should not be construed as professional advice / suggestion.
