Bad customer service

I have been with webafrica for a while now. Never skipped a payment. Now I need to cancel as my husband has lost his job and we are relocating and there just wont be money to pay for the fibre anymore. I cancelled on Wednesday morning very early. The lady who helped me told me that the fibre will be cancelled end of June, today I wanted to make sure my cancellation was done, and only to find out the cancellation was never logged, now they can only do the cancellation end of July, so I must pay for a month that I will not be using the fibre.... very quick to take the money every month but as soon as u need to cancel there is stories. Now I am told I should have cancellee it in May already for it to cancel end of June, we were only told on Tuesday afternoon that my Husband will be finishing end of June. I was previously told when I wanted to cancel that it has to be done on or before the 1st of the month, so wednesday was the fisrt nou I cant do it on the first it has to be done before the first... I need this cancelled by end of June as I was told it would be or the next tenants just wont be able to use the line as I will refuse to pay
