Unsatisfied client

I am now being ****** by VUMA . My debit order date is for the 1st of every month how ever from the 26th onwards I messages were they tryin to debit my account and if no funds available my wifi gets disconnected by the 28 I'm paying for a 30 day service but I get disconnected before the 30 day. Last month when I consulted with 1 of the agents Phumeza P from the network provide who is Webafrica I was told that my debit is for the 1st every month and when I asked why I get disconnected before that please go back and check I was told that they don't have previous records due to them migrating to new systems . So my payment was done on the 30 August and this morning I get an sms stating they tried to debit my account which is 4 days early . So now I'm being ****** for four days of internet service.
