unfair treatment

Hello

my first interaction as on the 28th of April 2021 and the gentleman assured me the services will be cancelled and collection will be done, he even promised a refund for the 2days remaining for the month of April, still I saw a green light on the device till 4th may i call and was promised again the device will be collected then disconnected.

25th may my account is debited and i speak to a Manager called Kabelo (i think) and was promised that a refund will be processed once the device is received he will also send me an email so I can communicate directly with him but that was not done, device was collected on the 27th may and no communication till I speak to Errol today who all of a sudden wants to investigate usage and the actually my refund will not happen, ignoring the fact that it's not my fault device was not disconnected and collected on time, and all the pain a suffering after I was honest with the company from the beginning, that I will not afford May.

I just need my R699.00 refund , please

regards.
