downgrade 10MB line to 4 MB ADSL

On the 30 Nov I requested that my ADSL line be downgraded to a 4 MB line, I was told this would happen within 3 days ref number for the call: ***a at the most, on 6 December I called Telkom again and still I have not been downgraded with the excuse they had technical problems and that kit would happen. On the 14th of December I called Telkom again and still I was on a 10 MB. I spoke to another lady and the request was reloaded ref number: ***a. On 21 December I called Telkom again and it seems that the request is still not finalised. I logged a dipute ref no: ***4 and requested that I be billed for a 4 MB line from 30 Nov onwards<br> <br> This is totally unacceptable and these requests that are not han dled correctly wastes my time and money.
