Telkom worst customer service ever

A few month ago i asked Telkom to increase my spend limit, of which i was informed that i would have to pay the amount I am increasing with at the end of the month. I paid the additional costs to have my spend limit increased and have some amount ready in the event i need to buy data/minutes and then just pay back the amount I used. Now I have no spend limit and wait an hour on a call as there customer care number account option does not give you an option to speak to an agent so i have to wait for retentions department. I finally get in contact with an agent just for him to tell there system is offline i have to call back in an hour. Your customer service is absolutely pathetic.
