stinking attitude

On the 02 of Feb I bought a gazebo at makro,on promotion of R1090 well that's Wat was written on the gazebo, got home checked my slip I realised that I was charged R1299 for it then I called the store n spoke to one lady n she put me on hold said she was checking with a relevant department, after few minutes a guy got back to me and said yes the gazebo is R1090 and I mst come back to the store with a slip it will be sorted out..on the 3rd of Feb I went back to the shop and I was sent to about 5 people explaining the same thing, finally lady by the name of Maria skosana was referred to help us, didn't greet or look at us me and my husband jst took the slip n left n came back n sarcastically made a comment abt me and my husband standing like we at marabastad my husband asked her wat she meant and she never responded jst processed the refund n gave it to me, with no single apology for the inconvenience after they billed m incorrectly n after I drover back to the store after they told me to...this is totally dissapointing considering the amount of money I spend at makro the attitude of all the employees I dealt with was unbelievably dissapointing..don't think I wanna keep the gazebo
