Broken authentication system needs to be addressed ASAP!

The MTN system to "validate" your identity via thumbprint is broken and needs to be addressed urgently. I went in to open a new contract and had to wait more than two hours while the system continuously tried and failed to authenticate me. I was not the only one, nearly every single person had the same issue and staff has stated that it is an issue ongoing from last year! I had to come in the next day and still had to sit another two hours while staff tried in vain to work with the broken system! MTN you are frustrating staff and customers alike. I cannot begin to imagine the amount of business you are losing, as frustrated customers walk out. I will certainly not be returning when my contract is over and will be warning everyone I know not to come into any of your stores, unless they have 2-3 hours of their lives to waste.
