Poor poor service

I went to Capitec Bank branch in Galleria Mall, there I was assisted by a nice lady consultant. My query is changing the debit order deduction frequency. The consultant wrote an email on the 15th of May and she promised me that the main branch will contact me by Tuesday the 18th.

Came the 20th debit order date all is not changed and bank has no funds! 28th I went to Galleria same consultant, this time she took my number promising to call me herself because the delay is with the It department . Until today the facility is not debiting and my credit score is affected while I wait for what I don't know. Went to visit Stanger branch the guy called the department still asked to wait. What's so heavy that IT has to lift to take 26days to solve my problem?! Poor service shame!!!
