Pathetic customer service

Went into Bedford center Nedbank ,was screened by the lady that issued tickets and was directed to normal counters, being a business client I asked for a business manager but was directed elsewhere, was there at 11.14 , 2 tickets were issued to me and out of frustration I walked out at 11.58 coz my numbers were never called yet people after me with the same number went through, complained and it fell on deaf ears.i don't have time to waste in the bank with staff that are not happy in ther job roles.
