Bad service

I recently upgraded to Rain-one. I called Rain to cancel the old subscription and fir the to collect their old router. The guy who was assisting me, informed me that he could not do the cancelation as he had 'system issues'. He stated that he will forward my cancelation request to his supervisor for processing. He said that the cancelation will be effected on 30/09/2024.

I called Rain to enquire about the cancelation, only to be directed to their website. When I get to the website I filled in all the necessary info and when I want to submit, the submit button is grey and cannot be pressed. I called Rain again, they referred me to 'the relevant people' to assist. Then the telephone ring and no answers or it rings until cut-off.

I have a good mind to cancel both router at this point.
