CANCELLED NOT CANCELLED!!!!

It is pathetic that I phoned your cancellation department on the 30th of June 2022 to cancel my contract and switch it to prepaid due to the fact the I am leaving the country. Contract is still going struggled days and days to get hold of your cancellation department and finally today got hold of them as I am typing now, I have been put on hold twice and this phone call is reaching over 40 minutes now. The operator over the phone said I requested an upgrade which I never did I strictly asked your cancellation department on the 30th of June to CANCEL my contract and the operator I was on the phone with still asked can she switch me to prepaid so I can keep the number for when I am in country??????? OMG how difficult is it to cancel my contract and switch to prepaid.
