Poor and slow service in line with their 1.4 star rating

I requested a statement from Wesbank from about 12 months ago for tax purposes. after more than a week I got a reply confirming that statements were sent which I never received. I enquired to which email address they were sent knowing how careless call centre staff are. More than a week now without a reply.

I also enquired why there was a 95% increase in the interest charged on my latest invoice. The reply I received was that this is a result of the 0,25% increase in prime interest rate. Poor math , poor service. After a week I am still waiting for them to show me their calculations substantiating the charge.
