I want my refund

Worst customer service ever On the 22nd of November 2022 i made a purchase at JAM CLOTHING (SPRINGFIELD DURBAN) the lady that was assisting me made a double transaction for R400 twice on my account .I then returned to the store to let them know that they have double charged my account .My matter was not attended i still haven't got my refund i have been sending email to Vinolia Chetty but i never got a response. Called numerous times to your number but no one is picking up. For 3 whole months i have been asking for my refund i even have proof of emails and phone calls. Always spoke to the same person by the name of FUTHI NDLOVU but no assistant worst customer service
