Extremely poor service

I sent an online request on the MTN website to upgrade my plan. I received an immediate auto response to my query saying that a consultant will get in touch shortly. However that was the end of all communication. I then called the MTN call center and was then passed from on consultant to the next , sad to say the consultants had no clue how to resolve my query of upgrading my plan. The level of competence is quite shocking. MTN please check out your recruitment process as you are entrusting your brand with people who think they are doing the customer a favour. Some of your customer consultants are shocking in how they communicate and then just pass you onto a another department where you are met by more incompetence. If you are planning to join MTN, please run far away. They have lost the plot as to who pays their salaries.
