Telkom bad service

I renewed my Telkom Lte contract on the 25 Oct 19 to date I have had the worst connection I have logged a case on the 26 Oct still waiting for a technician to call me have phoned the call Centre 3 times with no results they speak to you like they are doing you a favor by taking your call and yet the bill arrives on time very disgruntled customer to say the least what are my chances in cancelling my contract to find someone that will assist me any feedback would be greatly appreciated thank you
