Bad service and bad attitude

I bought belts on the 3rd December 2015, recently I notice the damage on one of the belt upon returning it I was met up with staff who were unprofessional and arrogant. I indicated that I lost a proof of purchase but I still had an sms that showed the sale but the lady was not interested in that. She told me that there was no way the belt could have got torn on it's own, it's either I took a wrong size or I have been wearing it everyday. What really annoyed me was her insinuations. I have never been treated bad in that shop I even told them I have always bought at Foschin but the treatment was bad. It made me think that Foschin staff are only interested in a customer only when it benefits them, they don't care about value for my money, why should I keep something that is no value to me yet I paid for it. I am very disappointed,why would I pay for a belt that will only last me 2 weeks. Is Foschin now a Parkistan shop where you know there is no value for your money. I was hurt by the treatment and the fact that I wasted my time having to go back there to demand quality which the shop always claim they uphold.
