No Response to my concerns

Hi, I emailed Cell C on the 15/02/2016 regarding a refund and about the contract account that is still showing as open at the credit bureaus but the account is already closed; I received the following automatic message: Thank you for contacting Cell C. We have received your email and one of our consultants will contact you within 24-48 hours. No one has contacted me yet and today is the 19/02/2016, Can one of your seniors or management please contact me urgently because I`ve put in my email that my concerns should be sent to your social media department, Please update the information at the credit bureaus and please contact me
