UNSATISFACTORY CUSTOMER CARE

On 13th May 2024 I purchased by online shopping a washing machine. There was a glitch on website and erroneously TWO washing machines were ordered. Noticing TWO payments of R7,500 deducted from my bank account I immediately contacting MAKRO to cancel 2nd order. Between 13th & 23rd May washing machine was delivered. 23rd May 2nd machine delivered and sent back. Numerous telephone calls to Customer Care & Montague Gardens store plus chats online to request a refund for send purchase and now as at 20th JUNE I cannot get a satisfactory answer. Some say that money is in account and some say nothing. Please can you assist.
