Very Bad Service Telkom

I have been a client of Telkom for past 5 years I had an Telkom phone line and an uncapped ADSL line the 7th of November 2017 i went to Shop at College Square Bloemfontein and cancelled my Telkom line and ADSL line I then took out a Wi Fi Contract Every month when my account comes it still showes that i have the telkom line and ADSL line But they switched it of 7 November 2017 Now my name is on bad credit and i have been back to the shop 5 times Each time they say that it is sorted out and they give me n new referance number I again recieved a new statement this morning and they still charge me for it This is really very bad Service
