VERY BAD SERVICE

I called Telkom 3 weeks ago on Customer services number 10210 to try and resolve a voucher pin. I initially held on the line for 1 hour and then was put to another Dept and again held on for another half hour before I dropped the phone. The next day again I tried and held on for 45min before someone responded. They took my voucher number down and my telephone number and promised to call. Three weeks have gone and I have tried everyday to call them and hold on the line for more than half hour before I drop the phone. I managed to get through after holding for 45min and they just put me through again to another Dept. I am at this point at a loss for words about how pathetic the service is.
