Telkom is busy *****ing peoples money

I filled in a disconnection of services form and handed in at the Clearwater Mall branch on the 10th of October. My service was not disconnected despite multiple visits to the Walk in center and calls to the 10210 and 10213 numbers. My line was eventually disconnected on the 18th of January. I was billed in Nov/Dec/Dec for a total of R2738.23 (3 months full service vs 10 days of Pro rata for November only based on the 30 day notice period.) When calling in to request a refund it first had to go in to disputes for 21 working days and the a further 7 days to get my bill which happened today. they are offering me R1516.80 back which is only 55% of the money paid in I guess 10 days of Pro rata service costs me R1221.43, when my normal monthly bill in in the order of R900. Today I called in after recieving the bill only to be told that it will take a further 7-14 working days to receive a call on how the refund was calculated????
