Unhappy

Good day

I purchased a Maxxus climber and the Genesis Duravac from one of your stores in Blue Route Mall on the 28/07/2017 with my Verimark credit card.As per the sales person, i have a 30 day customer protection act to return the goods if im not entirely satisfied with what the products can do for me. I told him the slip says 15days , and he said "yes" , thats Verimark policy , but the consumer act will allow me to return boths items within 30 days if not satisfied , i must just keep the receipt.Now im trying to call the store on (021) ********** and the telephone rings forever and a day, i was hanging on for 45minutes per day with no one answering. I called the centre management and left my details for them to return my call and up till now no one has call me back. I want to return the the vacum as the pipe is broken . Before actually doing the purchase , i recieved an sms stating that i will recieved a R250.00 off my first purchase over R799.00 . My first purchase was R2999.00 and on my statement it does not show the R250 off my first purchase. I just need this statement to be amended before i tart making any payments please , and i would really like someone from that store to return my call , as this is actually frustrating trying to call the store to inform them what i want to do. They give excellent sales services , but when you actually need to call them after the sale , no one seems to be bothered.
