Bad service delivery at Russels

I went to buy a fridge and requested that I was going to pay for the product on this Friday and then collect the product on Monday because I have my own bakkie. The saleslady and shop pushed me into paying for delivery so that the product can retain its warrenty The shop has pages paste on selling points to advertise the advantages and convenience to use their delivery. I paid for the delivery and it was promised for delivery on the same day at 13h00. At 14h00 I phoned the delivery person and he promised at 16h00. I phoned again and the man said he was on the way. The product was then promised for delivery by 18h00 and the it was raining.....
