Contract Cancellation

My name is Sekedi, i had a cellphone contract with Vodacom, which i have paid in full. In June 2020 i called to have them arrange cancellation as the contract was coming to an end and i was told the last installment was end of July, then in August i took my time again to call them and have the contract cancelled as it had ended as per the contract, To my surprise the debit order went through, again in September

which i called i was told the system had an error before updating the cancellation. Then in October again i had to call them and i spoke to Phumeza who processed the cancellation and said my query was sorted. again on the 27 of November 2020 i called after another debit order which i reversed i spoke luckily again with Phumeza , she then transferred me to Sarah, then she also transferred me to Janie and she also Transferred me to Oscar who said i don't have to worry anymore the cancellation was done. then now 4 months down the line i received a call from lawyers saying i owe Vodacom and i was handed over. Then i took again my time to call Vodacom and spoke to Nhlanhla who said to me i can see it on my system. she said i will personally escalate this before Good Friday and get back to you within 7 days as we didn't count the public holidays till this day she hasn't bother calling me. Please can Vodacom sort this out as they are really tarnishing my name for nothing. If i have to post this everyday for them to help i will do so. This is so said and i regret using them again after my first experience with them as well.
