Disheartening experience

Paid my R700 deposit for the adsl line on 11 June 2018.first they couldn't find my payment so I went to the telkom store to help them find it.im still waiting for anyone from telkom to call me to tell me when I will even get my adsl line installed.ive been calling the sales department since last Wednesday and their systems are still down today.im totally disheartened and I really don't know how such a huge company is still in business.
