Bad attitude with House and home staff yet 1 lady

We purchased a mattress from the above store yesterday , we were under the impression it was Double base and mattress , we only discovered that it was a queen size when we got home, I phoned this morning and was told that to change the order would take 4 to 6 weeks ? I said I would come in and cancel the order, I went in after work only to discover I had left the slip at home , so the unhelpful cashiers said they could not help , I insisted on seeing the manager and all was sorted out. There were 4 lady's behind the cashiers section , Boitumelo came in when they said it couldn't be done and I send nonsense , she got permission etc and I could see she was getting irritated with the other 2 staff members.Daphne was working with Boitumelo and she was great as well , but the attitude of the other 2 to their fellow colleagues and customers was totally unacceptable I was there today at about 11.15. I am sure you could find out who the staff were. We have gone elsewhere for the mattress .....
