Spec savers

I bought spectacles for my grandmother on the 05th of January 2021; and made payment on the very same day, unfortunately she passed on the 06th of January 2021. I immediately informed Maponya Mall Spec-savers of the incident and they promised to compensate me full payment within 21 days. I then did follow-up as I didn't receive my refund as promised but I was advised that management will contact me. I later escalated the matter with their Head Office but still didn't get my full refund as promised. Patricia then contacted me on the 11th of February; said they made decision for me to come collect lenses but without the frames. I asked her what should I do with those lenses?
