Pet Department SG review for SELLY ‑ Promotion & Pricing

Been using the Selly app for months as they had the option to input discount code at carts page. However, recently a customer informed me about issues with the discount codes and we found many flaws. The discount code in carts aren't able to detect NEW or RETURNING customers. Approached customer service for help but didn't get much, slow replies with communication barrier too. Everything else was good though but time to find an alternative....
