MTN ???????? No words i can write here will describe my frustration.

I have been a customer of MTN for 25 years. I have been trying to sort out the voice mail service on my phone. After numerous calls to the customer service center where we are issued with reference number and promises that the matter is escalated to the relevant department and even promised call back from supervisors, i am still waiting patiently for some sort of action to be taken. Customer call center agents are just reference number generators and have been taught the one word " escalation" , The only thing escalating is my blood pressure. "How can i make your day" is the quote that your staff use when answering but they only manage to generate another reference number and promise of escalation. I have no idea where all these so called escalations are going but it seems that they are lost in action, because there is no action. Please MTN get your act together and train your staff. Please arrange for someone that has an inkling of knowledge and some willpower to do some work to call me so that they can assist me on my problem. The last reference number is ********** 55
