Nedbank incompetence personified.

My mother received a sms from Nedbank stating that her card had expired. She went into the branch and they stated that she must contact their head office and gave her the number. She then telephoned the main branch regarding the matter, however they insisted that they did not have her cell phone number. She explained very nicely to them that they had sent the sms to her cellphone and as such had to have her number, however the person she spoke to did not seem to understand the import of this statement, and they continued to state that they did not have her cellphone number. She then tried again and was given the exact same story. This has carried on for 2 weeks now. There are no words other than: " Makes you think doesn't it.?"
