Contract not being cancelled

Good day <br> <br> On the 16th of November i was contacted by the telkom call center with regards to my cancelling my contract . I then spoke to the agent and told her the reason for me cancelling my contract an she then advised me to take out a data contract as it will be beneficial for me. I then agreed to the data contract of 5g and she then said that they will include a 45 minutes to the deal for the 1st 6 months . Today i got a sms to say that my data is up . I was then shocked because how can 5g be used up in 3 days . i called the call center and the lady told me that my contract was not cancelled and i was still on my old contract . This cannot be as my old contract is for 5g of data with 100 minutes and my minute allocation was just 45 minutes . I was transferred to so many areas and i am no closer to getting this sorted as the phone just rings and i am put on hold . This is the worst service ever and all i want now is to just cancel my contract and end my dealings with Telkom. I have had enough of this unprofessional and horrible service .
