Telkom Always High Call Volume

I visited the Telkom store @ Reds on 18 May 2015 to apply for a telkom line & an adsl connection. I paid a certain deposit amount in cash on the same day. I received a sms from Telkom stating that they havent received my deposit & can't schedule my installation. I called 10210 immediately & hang on for several minutes until i got through & was transferred to 3 different departments just to confirm that they have received the payment. Once i was done the last consultant advised that she is busy scheduling a date & time for installation in the next week or two & that her system has an error & cannot continue but will sms me the confirmation. I hadnt received any sms & called Tekom the next day of which the consultant advised that they do not schedule specific dates & times. The technician will call me to confirm on the day they are able to do the installation. I have tried several times to contact 10210 which is the only contact number for Telkom services, held on for 6 minutes yesterday and close to 12 minutes today of which i had cut the call because of holding on too long. This is basically EVERYDAY ANYTIME & is very frustrating. I would like my services to be seen to ASAP!!!
