I changed my earning preference from points to miles in early August. The miles haven't credited to my airline account for my 6 stays since. So, I emailed IHGCare. Their comments are shown <<...>> & my responses back to them are below. Is there any hotel program whose service is worse than IHG?

<< Please allow up to 3 weeks for the points to be posted to your Thai Airways account.>>
I have waited more than 10 weeks before contacting you.

<< After this time frame you will need to contact the Airlines customer service, we do not have any control or access to any information once they have been sent to the Airlines.>>
The airline tells me that they have not received any miles for my account from IHG.

<< We apologize for any inconvenience this issue may have caused you as we value your patronage.>>
This does not appear to be so as you didn’t bother to understand my email & haven’t done anything to justify your self serving misstatement.

<< please feel free to contact the IHG Rewards Club Service Center>>
IHG’s Service Center always fobs me off, just as you are doing now. Every time I have shown to be correct & your service center wrong.

Your response is miserably inadequate. This issue is with IHG & I request that you address it properly.
