Appalling, appalling, appalling service - rather don't visit the UK at all. NOT WORTH IT

The levels of appalling and unacceptable service must actually been seen to be believed. From security making elderly customers sit on the floor outside until the exact time of their appointment (despite their being a completely empty waiting room on the other side of security), to the exorbitant charge to scan your documents in house one is left with the feeling that all TLS is interested in is taking as much money as they physically can from people who have no choice but to use their services. There is ABSOLUTELY no way to track your application without a) physically going to the centre in the hopes that you may find someone who actually cares enough to give you some guidance or b) call the UK Visas and Immigration service in the UK, I have currently been on hold for 20 minutes and am struggling to control the levels of frustration and what feels like thievery on the part of TLS. R1800 (plus R458 to scan) for what?? RATHER HOLIDAY ELSEWHERE - IT IS ABSOLUTELY NOT WORTH THE MONEY OR THE TROUBLE. I am absolutely disgusted by this company.
