Disgusting customer service ever in my life

I am very angry with the service i got from ackermans call centre, they have send me a wrong link to do my payment, after i was done with my EFT payment they send me another message apologizing that they have send the wrong link, i called them to get to the bottom of the 2 messages i received using my airtime holding for a long time still there was no solution, still the money that i paid they don't know how to rectify it, i have send them proof of payment to the email address they gave me but still no solution, everytime when i call they give me different email address, i dont know how to solve this problem😲😲😲what a bad service they have.
