Debited twice on different account

<p> </p> <p>I have two problems with Cell C, firstly I took up a contract with them where I took a Laptop and on delivery that’s where my problems started, this guys came to my workplace only to deliver a sim card while I app**** for a laptop and when the laptop was delivered, it came back with another sim card that i never and as per call recording agreed to a second sim card. Secondly I changed my bank and reported the issue to you guys then you debited on the new account and today you debit me on my old account, please REFUND the amount that you guys have taken and cancel the openline number as i never requested for it.</p>
