Bad customer care

I app**** for a new contract with MTN online more than a month ago, i got a e-mail to say that it is approved and that i will get confimation soon. Up untill now i never heard anything from them. I thought by going to MTN the customer service will be better that Vodacom wich i have none stop problems with but it looks like all cellphone companies in SA is the same and dont need new business. This is so bad for such big companies to not care about there clients or new business
