after sales service is shocking!!

Good day<br> <br> I upgraded one of my 5 contracts a few months ago, after many issues including the incorrect device being delivered, I found out after the upgrade that I was put on the incorrect package, a 200mb data package instead of the 1gb smartdata that I asked for. So I phoned the call centre on the 20th of Oct to have billing refund me for the very overpriced 200mb package I was incorrectly put on, seeing as though it was an error done by the upgrade department and the data was never used. Well, today is the 11th of Nov and when I called in to the call centre they advised me that there is no feedback!! After 23 days, there is no feedback?! Does anyone actually work in the billing department because if I took 23 days to resolve a query when I worked for cell c in the stores, I would have likely lost my job! Please could someone give me feedback on this matter, my query number is ***
