Bad service

I have installed WiFi at my resident in Dec 2016. However since it was installed we could not use the WiFi properly. It buffed or it just didnt work. I have complained and nothing came of this. In 2017 Sept i went to Telkom Tygervalley to cancel my contract. I was assisted in English only..I then asked to be assisted in Afrikaans...then i had to wait 20 min. Still no assistance. I then went to the store manager...he told me he cannot speak to me in the office...we could speak just there. Eventually he told me if i want to cancel i must fill in a form and e-mail it to billing department. I did not cancel my contract because of penalties. I just want a print out of my data usage since Dec 2016 up until Oct 2017. No response. I have been paying for uncapped...why cant i use internet at home. We only at home from 3 in the afternoons...R599 for **** service...dont i have the right to see what i am paying for??First bill i got was in Sept 2016...after i complained.
