Inconsistent Quotes and refusal to do business

Jefo quoted us on a 500 x 500 security barrier R 1 000.00 including 4 additional pieces of angle iron to secure it better as they were just ripped out. Another person was quoted R250.00 with no angle iron. Now they refuse to do business with me as I queried this as I cannot believe that the angle iron is R750. The most amazing thing about all this is that they claim to be christians with bible verses on their business cards. Look if I were you, I would steer clear of this company. They do not know what they are doing, their security barriers were ripped out by hand and they are unpleasant and rude. The owner is Eddie and he cannot do business. STAY AWAY......
