INFURIATING!!

i called Telkom to apply for a new line and them to install and connect my household to WIFI. i was asked to pay R700 deposit and once paid they will come and install. i paid the R700 and couple days later got the invoice and SMS stating they will be at my home on Friday 09.02.2018 between 8-12. They never pitched, i never got another SMS for a new appointment, i have tried calling EVERYDAY, FIVE time a day to be ON HOLD FOR OVER 20 MINTUES at a time. if i go to another department they tell me they cannot assist and i need to call 10213 for new sales, i have told them that i keep calling that number for new sales and hold for over 20 minutes 5 TIMES A DAY! imagine all the time i am wasting and money i am being billed and charged. what is happening now, i have paid the deposit and now no one coming to install it. i made arrangements for someone to be at my house and have wasted their time too!! WHAT IS GOING ON?????
