No service

I have been trying to upgrade my grans ADSL for a few days now. I would like to stay with telkom as its easier but you certainly making it hard. After hours on the phone the last few days, we get told to call technical. They tell us to call sales. One person says we can just upgrade, the next person says we cant. Then we on hold for 30 mins and nothing. We cannot get an actual answer or any actual help. Do you prefer we cancel you and give our money to someone else???
