Bad service, I need my refund from Bradian Logistics

A month ago I took in my cellphone to Telkom Sandton City store in for repairs and I got good service from the tech guy who took all my details (including which insurance company I use). He then explained to me I will get an sms with an amount which is the access amount to pay for my phone before being repaired. He continued to explain that automatically Bradian Logistics will see which insurance company I use from their side, it should pop on their screen when they enter the reference number. After about 4 days, I get an sms from Bradian Logistics saying I need to pay R2500, immediately after getting the sms a lady named Sylvia called me from the company saying I need to pay soon so they can order parts for the phone. I then pay and called her back to ask why my ACCESS was so much when I pay for insurance of roughly R380, she then said why did I not tell her I have insurance and I told her Telkom said it should appear on her side automatically. I tell her I need a refund before they continue with ordering parts so they can resolve this issue amongst themselves before repairing it, she ordered me (rudely) to go back to Telkom and ask them for a screenshot of the email to book in my phone, I explained to Telkom and they sent the email. Bradian Logistics did not respond to their email and the next week they call to tell me my phone is repaired without my knowledge, I ask Sylvia who gave her the go ahead without refunding me and why she did not respond the email she asked me to tell Telkom to send, she the shouted and gave me the worst attitude and said it was me and Telkoms fault and I will not get my refund from them, only to find out she even missed one number/alphabet on the reference number hence she could not pick up which insurance company I use. I hung up and called again to speak to her line manager Paulina, who was friendly, she emailed Telkom but she did not take blame for their error and said Telkom will have to pay me back. I went to Telkom more than once, no one seems to know whos suppose to refund me, Bradian Logistics even sent the phone back to the store fixed. I need my money back from this company and their service is appalling. It has now been over a month with no one contacting me with a solution.
