Pathetic service at Markham Cresta

Markham Cresta branch pathetic service.On black Friday my card ,which was too old could not be swiped the shop assistant ask me to go fetch my ID at home. I went to fetch when I came to the store to get assistance on obtaining a new one the consultant conives with the customer care consultant on the phone from the contact centre to say that I failed the security test when i was asked 3 simple questions like where i stay or if i got an account with mtn. I'm sure because they were about to close shop for the day .(their closing time is 7pm on fridays I was there by 6.30pm).They decided not to help me on the basis that I have a Zim passport.The behaviour displayed was xenophobic and unprofessional especially considering that its customers who make them have a job.
