Stay away from Experts SLASHCART Muhammad Usman/ "Sam"

Topic summary

A Shopify store owner warns against hiring SLASHCART (run by Muhammad Usman, also known as “Sam”), a Shopify-endorsed Expert. The complaint centers on two main issues:

Primary Issues:

  • Failed to complete paid work as agreed
  • Illegally provided a “bootlegged” paid theme claiming it was free, resulting in the store owner being forced to pay the actual developer

Resolution Attempts:

  • The complainant documented extensive evidence (50+ screenshots, screen recordings, messages) showing harassment and misconduct
  • Submitted all documentation to Shopify but received no response
  • Eventually recovered payment through a bank chargeback after several months

Ongoing Concerns:

  • SLASHCART remains listed as a Shopify Expert despite the complaints
  • Another victim recently contacted the original poster reporting similar experience: paid money, received no work, and was ghosted
  • Harassment extended to the store owner’s customers

Advice Given:

  • Never pay experts before work is completed
  • Consider posting reviews on Google Reviews, TrustPilot, and Clutch to warn others

The discussion remains unresolved regarding Shopify’s vetting process for endorsed experts.

Thanks. The most shocking was the way it was handled by Shopify. I uploaded about 50 screen shoots to show them the harassment and the correspondence between myself and SLASHCART and they never responded.
I had documented EVERYTHING. From screen recordings to screen shots, to messages between SLASHCART and myself.
After selling on Shopify for 8 years, you’d think they’d have handled it differently.
Most appalling was my customers reaching out wondering why they were being harassed. I documented that too and sent to Shopify. SLASHCART still is listed as a Shopify expert. Mind boggling.
