Telkom Owing A Refund

My Mom upgraded her internet bundle to a Smart Broadband 20G a few months ago.<br> They charged her R1480.00 admin fee which was said would be refunded, it wasn't.<br> We have been in store 3 times and on the phone, a case number was received and said the issue was resolved.<br> Now the statement says this transaction was refunded, but now they continue to take 399.00 off her account and 399.00 off the 1480.00 that has not been refunded, charging her double. Absolutely shocking service!!!<br> Please fix this and put the R1480.00 back into her account immeadiately.<br>
