Unable to reach Telkom contact centre

Account no *** I purchased a 10th Bday Monate Bundle - Voice minutes 500 All network (30 days) package and unable to make any calls, when I call it states that my "balance is insufficient" When I check the balance I have 483 minutes and 53 sec available till 10/04/21. Tried calling the 180 contact centre number to speak to someone and only have the option to select preselected option and does not let you speak to a person. Can you call me urgently to resolve the matter as it seem the only way to reach someone at Telkom is to log a complaint on Social media.
