Empty promises like always from telkom

Almost 2 months now that ive been waiting for Telkom to refund my money. Ive been charged for a 10 meg where there's only 4 meg available in my area. The 29 January a lady phoned me from telkom and asked if my line was working .I explained to her the same as i explained to about 5 people that phoned me that ive got a problem where ive been over charged and as soon as you tell them that they tell you that they will be in contact with the correct department and someone will phone me back.2 months now and every time same old story.This lady that phoned me on the 29 January promised me that she or someone will be in contact with me about my complaint within 5 working days.She had to get them to investigate why i was charged for 10meg. I even explained to her that my line is switched over to 4 meg now but even my recent bill i was charged for 10meg. her 5 working days turns out to be 8days till today and no one bothered coming back to me.Every time i have to post a complaint to get someone to reply saying that they are investigating the matter and someone will come back to me and when someone phones \ they will come back to me"Always same old story.TELKOM GET YOUR ACT TOGETHER"""
