Vodacom worst service

I have been using Vodacom for my entire life but in this case i am going to review the company as the worst-case ever, i have called Vodacom regarding my contract cancelation from March 23 2021,i called again on the 23rd April 2021 to make a follow up, it was a month later, i asked how long does it take them to cancel the contract, they rep**** by saying it takes 24-48hrs,now is another month no feedback, no sms no email to confirm that my request is being looked at. For the fact that I explained clearly the reason for the cancelation, i don't know if they are expecting me to pay the bill, I am planning not to pay them so that they speed up my cancelation, It is more that 24-48 hrs of processing the cancelation, From March to May is 3 months and 1 344hrs of me awaiting for their feedback. This is the worst service that I have ever seen in my life. VODACOM HOPING THAT YOU WILL BE ABLE TO RESOLVE THIS ISSUE ASAP. Regards
