Pet Training Refund

Please advise if I have a legal leg to stand on to request a refund.

Last July I took our two dogs to be trained for 3 weeks with a company that claimed to be reputable and had 5 stars on Google.

The cost for both dogs was $4800. The deal with the training was that it included follow ups should we need it. These are dachshunds. If you knowyou know- stubborn. Anyway, the one dog has regressed and I reached out to them regarding the included followup. I called and spoke with the owner who said he was driving and would call me right back. He never did. I have called several times since. I've texted, emailed, and even left comments on videos they've posted since of other dogs they've trained.

So I paid nearly 5k with the belief that these ncluded followups were part of the deal and l'm essentially being ignored. Is there a value to the included follow ups that I could get refunded for? lf I'd known this would have happened, I would have gone with someone else. I did a lot of research before I settled on them,

Please advise
