Builders employees are trying to ***** my money using my account

i am so angry and fustrated right now.

last month i tried to place an order but it kept on giving me issues until i contacted builders, i was advised by one of the employees that i should add money in my builders account she will generate a quote then checkout for me. after some weeks of waiting for the order to be delivered i was advised that they won't be able to deliver the item because the delivery address is very far. my money was refunded back to my builders account, i then requested a refund form which they sent it to me and completed the form and sent it back together with the required documents. today i got a message and an email confirming an order that i don't know about. and the address is johannesburg and i dont know anyone in the city, i am staying in Cape town. Surely its one of the employees of builders who are trying to ***** my money.
