No payment after debit

i joined Vuma around 2 years and i have been paying by myself coz they keep on saying they cant do a debit order on my account so on the 3 June i saw their debit order of R399 and again few minutes after that there is another debit order going thru so I though to myself they wont debit in July. On the 1st July they debited again but this time I close everything for the debit orders. The sent me a message saying that they will suspend my service if I dont pay. I started contacting them telling them that they debited twice in June, and their answer was they only receive 1 payment in June. They asked for my bank statement, which I provided and still they say they only received 1 payment. To crown it all they told me today that they will be deducting today so that they can open my internet. I am still working from home and I am using the internet, so for 2 days now, no internet. There was a lady called Babalwa that promise to help me but since yesterday nothing. Webvuma is a **** that dont even care about customers, they just want to ****
