When a customercare don't take care

On the 22nd August I wrote an email to customercare. The reason for it?<br> For additional functions I had to establish an account at MTN. After doing this, the MTN system told me, that for my kind of contract this function is not available.<br> I know that these guys are talking people, because it's a telecommunication company. But I haven't assumed that they can't read. And on the other hand, the call-center is closed on Saturday at lunchtime for the rest of the weekend.<br> However - the reaction of MTN is ZERO. Neither care nor customer focused. But then they should'nt have a helpline. Make a closed shop, establish a network of dealer and everything is ok. But these ******** people are really frustrating. Please swipe the account I have established. I am not interested in collecting dead and useless accounts! The only benefit is getting more and more ******* adverti*****ts.
