Uniconnect Sim — Very rude customer staff

Very rude customer staff --- I was going to buy a Uniconnect sim for Singapore and i had some questions regarding recharging and currency and you know the regular ones before you make such a purchase.. Instead of helping me with answers Rohit said that I should have done some internet browsing on what they off the and all and then ask questions if needed. That was it.. Thats when i decided i wont buy their sim card. Not only was he rude but was least interested in taking up any queries!
