Worst service ever!

<p>I received a sms from MTN 3 weeks ago saying there's a credit on my contract account,I called them and a discussion of a refund was done,I was given a reference number and told I will get feedback within 3 days,it's almost 3weeks and I'm still waiting.I've been calling the customer service for the past week getting transfered from here to there with being kept on hold for more then 45 minutes every time.I called again now,was transfered to retentions 5 times and never even spoke to anyone in retentions because no one answered,I was holding and holding and I'm sick and tired of calling,being kept on hold for 45 minutes with no assistance.I think MTNs service is utterly disgusting.I'm a good account holder,never been in arrears and this is how they treat their customers.It's not as if I owe them money they owe me and I have to wait for help..</p>
