Bad Customer Sevirce

JD has made a double deduction for payment of my account i.e R752.00 x 2. I have contacted them telephonicaly on the 6th to request a refund and was told it will be in my bank account within seven days. The problem is i dont remember who i spoke to initially. Yesterday i called JD call centre to follow up because i have not received my money yet. i spoke to Lesego and she said there is no record of my request, i mut resubmit my request and wait another 7-10 days for a refund, i requested to speak to her supervisor. i spoke to Bongani Mnisi. he told me i have no proof that i phoned last week because i dont remember who i spoke to i am just making allegations that i cannot prove (implying that im lying). <br> <br> I dont understand why they keep on saying their calls are recorded for quality purposes if there is no record that i phoned last week and also i dont understand what Bongani meant that i don have proof, must i get and retain proof for contacting my service provider because they will be *********** to record my call/ query.
