Rapid locksmith are RIP-OFFS

I needed a cylinder lock replaced for a client, I called RAPID LOCKSMITHS as they advertise R295.00 call out - I asked for a quote, and was advised its site dependent, locksmith arrives - no quote, he just pulled out his drill and within 6 or 7 min door was open, lock was replaced, - last week I bought a cylinder lock R179.00 - today with rapid I paid R950, the first rip-off - I then get billed R1950.00 to install the new lock - max 6 min - and let’s not forget R295.00 call out - I paid R3195.00 for a 6min job - ABSOLUTE THIEVERY - what a rip-off - THIS COMPANY DOES NOT DESERVE TO BE IN BUSINESS
