URL Redirection After Migration For Service slug or multiple slug

[theballoonwala]

My website was in wordpress https://theballoonwala.com and now I have migrated to shopify and now new URL have collections in slug, I understand it's shopfy architecture and we can't change but the problem is old URL of collections wordpress was having different slug, which had services in between. I had done SEO on wordpress URL and even made backlink for same.  since I have migrated to shopify I want to redirect to old URL to new URL  but its not happening. I have contacted multiple developers and all failed to do. I cannot afford to loose my SEO money that I have invested in backlink.

Is there anything in shopify that URL has multiple slash or services in slug will not be redirected. Please check table with OLD URL.
