Comptech Inc

I visited this store looking for a replacement HDD and the owner of the store was present at the time, he sold me a HDD for 50$ and said " Its in saleable conditions" and told me that i had 60 days to return it for a full refund if in any case didn't work, I went home installed it and found out it was defective, I went back with the receipt to return it, but the owners assistant told me it can only be exchange. The owner lied to my face and they refused to refund my money...A TOTAL RIP-OFFI WILL NEVER SHOP THERE AGAIN!!
