Excahnge failing to support Area

Good Day<br> <br> Well the name state all the sadness of the complaint. Exchange TRHK is failing to support the area load. Number of time I have sent in complaints to Telkom for a possible upgrades but like most times they just say a phrase so you think they will assist. How can a costumer know, how many people is connected to an exchange to do a petition as they are stating you can get better speeds but during 16h00 - 22h00 speeds are disappointing with the exchange being overloaded.
