MTN new message center reading out phone numbers

For some months, MTN has insisted on relating the number from which my messages originate. I am sure none of the MTN customers sit with a pen taking down numbers in case they might need them and neither does anyone remember anyone else’s number any more. So, what is the point of the slow reading of every single number? I called the call Centre and asked if they could take it off as it wastes my time and I have stopped listening to messages as a result. They told me it is not an option to not be slowly read the number. As we are paying for the call, I resent having to listen to a number. MTN we are not fooled - you are prolonging the message for your own purposes but you will end up with no message center as no one wants to waste their time with this.
