vodacom bad service

as a custoumer for at least 4 years plus i never had any difficulty. In Nov i was due for a nem ****el they delivered it at home. As n student of NWU i only start using it in february and march. but since the i could not lock into the website, my first reaction was with covid and high volume of first years viea internet this system has n high volume my cellphone on cell c locked in immediatly. this let me go back to vodacom and the same person helped me each time with this smuck look on his face because it open the 3 tme i really complained they locked a call then they told me the area behind vodocom has problems but not actualy their problem when i asked what can i do they told me to speak to the person at the counter at the door he charged me 11000 to instal? to fix my problem i asked if i can cancel my contract but as it is know ii only start the 2year term. know iam stuck and i need to pay them for no service!!!
