THE hub Greenstone- we the reason thier defected dress broke

I bought a dress on the 28th Feb at the Hub greenstone. My daughter to wore a the dress to a wedding and the strap broke. Later on in the evening the second strap broke. I took the dress back to the hub the very next day to get a refund. They refused saying the dress is damaged. Of course its damaged cause what am I here otherwise. Anyways, the staff didnt help at all and imp**** its my duaghters fault. Don't waste ur money here. Rather go to ackermans or pkp clothing. Least they have some resemblance of customer service. Will never shop there
