Bad service provider... unhappy customer

Been with Fibrestream for a couple of months, have experienced connection problems, debit orders going off my account and fibrestream cutting my services,I then email them showing them proof of deduction going off my account and screen shotting the debit,and got a reply from Rebecca at Fibrestream...saying This means that a total of R449 needs to be paid in order for us to unsuspend your account. not looking into the problem with their IT guys and resolve the could be Technical erro as to why it returned as a return yet I sent proof of payment going off.The only solution I came up with was to reverse the debit order for them to then realize that it actually went off as the customer said and why must I pay reconnection fees of R150 when it's not my error
