The nightmare never ends!

For context, please refer to the reviews in December and January. Since December, I've been in a constant battle with Best Electric to ensure my debit orders are set up correctly. Their incompetence has resulted in numerous unauthorized debit orders remaining unpaid, tarnishing my credit score and causing me to incur fees. What's the point of having a CUSTOMER COMPLAINT DEPARTMENT if they are unable to resolve a simple instruction such as changing a debit order? I've spoken to various Best Electric employees and have been in email correspondence with Chuma David, the Regional Accounts Manager. Despite my latest email dated February 16th, requesting confirmation that the debit order has been removed from my account, I have yet to receive a response! Today, the freaking debit order went off AGAIN!!! I AM BEYOND FRUSTRATED WITH THE LACK OF SERVICE DELIVERY FROM BEST ELECTRIC AND WILL NOT RECOMMEND THEM TO ANYONE!! I truly regret ever opening an account at Best Electric and should have taken my business elsewhere where I am valued as a client. I do not have time to deal with this and am truly at my wit's end to get this matter resolved. Best Electric leaves a sour, bitter aftertaste in my mouth and is thus far the worst company I have had to deal with. Do you really not have the competency level to sort out a debit order? Is the only way I'm finally going to get this matter resolved to close my banking account to stop you from putting the debit order through on the wrong date since you obviously don't know how to do it!! It's been 3 months trying, I have HAD ENOUGH of all this incompetence, so please kindly advise what forms of recourse there are to get the matter dealt with. Can someone from a provincial level at Best Electric please get involved, as I am getting no joy from the regional level, or is being customer-centric not one of your priorities?
