INCORRECT INFO ON RECEIPT AND *********** OF STAF

i went to cresta to buy a couch on sunday. I already had one in mind as i had been there a couple of times and needed the couch urgently. i was assisted by Addis(sp) and they didnt have stock of the fabric i wanted. I decided to purchase 1 of the same fabric as the one onthe floor which is the Koda 3 seater stock code *** It was marked down to R6995. Paid half of the amount R3772.50 on the day as i had reached my debit card limit. Got the receipt ,Date of delivery confirmed saturday 05/03/2016 between 09am -12am.Went back yesterday to pay the balance of R3772.50 however when i got home & checked yesterdays receipt the i my order had changed to a 2 seater Stck code ***. i clled the store thisafternoon spoke to Mark and, explained to him that it has 2 be correct as i do not want the wrong thing delivered. i have already experience enough bad service from coricraft. as i was explaining to him he told me that, the original couch i purchased is not in stock and will have to wait 4-6 weeks fora new one. He was rude and gave Addis the phone wile i was talking. It turns out the original couch wasnt even in stock. i will not wait more than a week for that couch! Pls sort it out.
