Investec needs to live up to the News24 bank of the year award

Another disappointing treatment from Investec. Tried to contact Investec on their 24 hour customer service line over the weekend without success....just managed to get through to them now, only to be told that they cannot verify me as a customer. This, after more than 20 years of banking with them. They do not have a problem debiting my account monthly with one of the most exorbitant monthly bank charges in the industry, though.
