High volume of calls.... 3 Hours is rediculious

I have been trying for the last 3 days to get through to the call center on 808 from my mobile. every single time they say there is a high volume of calls, which is understandable i guess. Every time i hold on for about 40 mins listening to the jingle in the back ground and then the phone drops the call and i have to follow the procedure from the start again. How on earth is it possible that in 3 hours a day for three days consecutively you can not get a hold of anyone in the call center. This is unacceptable as we pay these high amounts of subscription every month but when you need just 10 minutes of their time there is no-one to be found. All i need is my statements in order to submit my tax return but no.... This is really bad and all of a sudden Cell c's offer to buy out my contract sounds like a not to bad idea, seeing that they cant possibly be worse than MTN.
