Terrible Service Received!

My sister in Law is unable to walk and therefore needed my assistance with getting her fibre so she can look for online work. I reached out to Axxess DSL (Pty) Ltd for fibre and they installed it but did not debit the account. In May this month they cancelled the fibre line and are charging us a cancellation fee. We provided proof that we gave the banking details and still nothing happened. We require this to be resolved immediatly as she needs internet urgently. Remove the cancellation fee so we can pay the months that the internet was used!!!
