ROYAL WENDY'S - RUDE SALES LADY

Ordered a wendy house from Royal Wendy's, the date was booked for 14 September 2020. By the 11th I have not received any confirmation from them, on phoning them I was told it is booked for Wednesday the 16th. Told the lady it is impossible as I made specific arrangements for the 14th. She became extremely rude and offered me my deposit back if I don't like it. Deposit refunded however I was short paid by R368.00, which I still have not received although I requested her to pay it back. If I could I would not even rate them 1 star!!
