Unable to get refund from useless branch manager Raymond for goods purchased online

Not a good idea to purchase anything online from Builders. Neither is it a good idea to trust that a store manager would be able to sort the issue with the refund, especially Raymond from Builders Warehouse New Market! Purchased two outdoor umbrellas online on 25 Nov. Collected from the Boksburg branch on Saturday 27 Nov, only to discover that the umbrellas are yellow in colour. Returned the goods to the New Market branch on Saturday 27 Nov. Waited 1.5 hours to be served. Excuse: only one person on duty at the online collections counter! I was eventually taken to the cashiers for my refund, only to be told that they are unable to refund me as the money hasn't been released from the Boksburg branch to the New Market branch via SAP. Store closed and I was still waiting for the "release". Was promised by the useless branch manager on duty, Raymond that he will sort the issue first thing Sunday morning and make contact. After not receiving any communication nor feedback I made contact with him at 13:14. Excuse: He forgot to make a copy of the piece of paper he gave me with his mobile number and therefore was unable to follow-up. Then rudely informed me that anyone can make a mistake! Oh really? He then dropped me a Whatsapp at 13:53 informing me that he won't be able to assist me with the refund as the money still doesn't reflect on his side. He will however follow-up with their head office in the morning and get back to me. Needless to say, I am still waiting. Not sure if it is the useless store manager or the "Builders...F@ck customer service attitude" which is the problem. However I've lost almost R1 200 due to nobody from Builders being able to assist me. So be warned, purchasing from Builders Warehouse online is risky and not really worth the effort.
