FREINDLY SERVICE

i called their call centre asking them to help me with the reschedule of an appointment on their system,i spoke to Thapelo who give me worst service ever,i asked why am i getting hassle trying to reschedule the appointment,he said to me i have canceled my wife appointment on their system and i asked if he can help me reschedule the appointment but told me he cant i have to re do it on the system,i told him i was struggling to do it but he told me to rebook and go to standardbank to pay again the appointment fee which i have already paid i asked if i can speak to someone who can help to place my money to the new appointment if i make it because money is already in their system.he kept me holding on on my mobile number until i got cut off ,i called again same situation happened i was cut off. i then called again and spoke Gugu who i iasked to put me through to Thapelo or the call centre manager or supervisor instead i was kept on hold until i got cut off again.what kind of service is this????????? they act as if the have taught people how to use their system.my wife visa expires end of the month and i dont have any income at the moment what must i do ??? i am unemployed the money i used to pay the vfs global fee i got from my family.
