Wrongly charged

<p>Good day</p> <p> </p> <p>I have upgraded my number I had for 10 years plus in August. this was done online free of charge. then last month they overcharged me with more than R200 per debit order I have a ref 1- ********** 31717 to do a credit still waiting no one called after i haved called numerous times. i was charged more my total should be R560 also was charged for a migration when was this done??? can someone give me feedback quick to take debit orders but slow and poor to credit. when you phone call centre you hold 30 minutes and when they answer they put the phone down :( bad for 12 years service with a provider.</p>
