Locktec are unethical and unprofessional

Locktec charged me R3500 to replace a broken lock. It took them less than 30 minutes. The invoice states R1495 for an Elzette lock. This lock can be bought online for between R65 and R250. They charged me R1695 for labour. And on top of that a callout fee of R325. They took advantage of the fact that I wasn’t aware of industry pricing and they did not provide me with a quote beforehand. I nievely paid the invoice once the work was done, because it was too late, it’s hard to argue when the work is already completed. Only afterwards did I realize that I had been totally *****ed over. Don’t be fooled by their low callout fee. These guys are unethical and unprofessional. When I queried the high fees, I got no response. I hope nobody else gets caught out by these guys.
