IMG International Medical Group They won't pay a legitimate claim after 3 months Indianapolis Indiana

I purchased health insurance from IMG for a trip to Mexico June 12, 2021. Had accident while on trip and filed covered claim with IMG formally on 6-14-21 using their online claims service (including sending in all required expense receipts) for my claim which was covered by my policy.  Claim was assigned and was supposed to be paid out in 1-2 months.  on 7-26-21 called IMG and was told claim was being processed. 

Called back 7-22 and told same thing and that processing would take 1-2 months.  As of 9-13 still have not been paid in three months- spoke with Kim and she said claim was being "escalated".  9-28 called again and spoke to Donna and she said it was still in "processing".   I asked for a supervisor and was told supervisor said to call back in 3 weeks. 

That would put the process at 4 months.  I may never get paid.
