Frustrated about the service I got from Telkom cellular and I want my refund😤😤😤

I had a contract phone with telkom and it ended in November last year and the cancelation of insurance wasn't done and it accrued the charges of R431. 44 which was paid in November 2021 to be settled and to my surprise on 17th and 23rd Dec same premium was deducted twice and I've logged the case ***4 and spoken to several consultants which assured me that they will refund/reverse those two premiums to my account to my surprise I got a sms stating my case its closed without my funds being refunded and the same incompent consultants are not sure why the system hasn't refunded my money and they want to log another case which it's going to take another 10days before I get feedback.. What makes me angry they Will assure you that the debit order it's been cancelled from billing department but it's still going through to my account and the attitude I got from client services. All I want it's my money back and the cancelation of the debit order to be done and I've learned my lesson ever to open the contract with them and I wouldnt encourage anyone to do so as I've experienced the worst service through their offices even on their careline... If such service it's been tolerated I won't till I get the results been done.
