Poor Customer service, numerous complaints with nothing resolved

Endless problems with cellc, I've had 5 contracts with cell c at the same time. Unfortunately the customer service provided by them is extremely poor and for that reason I started canceling my contracts instead of upgrading them. 02/01/2021 one of my contracts is ending they require 30 days notice prior to end date that states I won't be upgrading, I called in last week explaining I will not be upgrading and I would like to cancel, after explaining thoroughly to the agent she wrongfully canceled the contract immediately and I obviously will still be charged this month December 2020 and January 2021 without having access to my benefits which is data and minutes etc. While writing this review I'm currently still waiting on customer care waiting to speak to a team leader for over 30 mins when I can hear them having a good talk and laugh in the background (VERY UNPROFESSIONAL) after speaking to an agent they say i have to go to a store to resolve the matter and reinstate the number. Unfortunately I'm working 7 days a week due to the festive season and finish at 7pm there's no way I can make it to the store in time, I feel that this matter should be resolved internally without me going to a cellc store as non of this is my fault. Furthermore this isn't the first time I'm having an issue with customer service as I mentioned above the reason why I'm canceling contracts. I would not recommend cellc to any family or friends as no one can help or assist in resolving issue and they wonder why cellc is in so much of "trouble" it seems like non of the agents or team leaders are willing to help they seem happy to come to work do minimal go home and get paid that mentally is pathetic as my end result I'd like my contract number to be reinstated as requested without going to a store and I will never take another cellc contract and definitely changing mobile network!
