"they are not moneys paid to rft... they are moneys loaned to rft by suppliers..."

how do you arrive at the idea that customer deposits are not deposits from customers but rather loans from suppliers of RFT?

and then you copy past a note that identifies exactly what a customer deposit is. Customer pays upfront (usually a portion, say like purchasing a house of the plan), RFT receives the cash and converts that cash into making a product (like a construction company uses cash to building a house). How does this process look like in the Asset & Liabilities.
Step 1. Assets = Cash; Liabilities = Customer Deposit
Step 2. Assets = Inventory of Raw materials; Liabilities = Customer Deposit
Step 3. Assets = Inventory of finished goods; Liabilities = Customer Deposit
Step 4. Delivery and Closing out the Entry. Profit or Loss = difference between what the customer paid for product versus the cost to you of making delivery of product.

You cannot just say that the customer deposit is owed by RFT and needs to pay it with current cash (this is only true if no product was made and delivered), you need to find the corresponding entry in the ASSETS of the company, viz. double entry bookkeeping.
