Bad service

Possibly the WORST SERVICE IVE RECEIVED!! I Received a email stating Debit order was not received or it was rejected.well I email proof of payment and checked my bank statement to make sure payment wasn't paid back into my account.nothing was paid back into my bank account.Vox was the first to debit my bank account on the 26th August 2022. I get no response I Emailed again and Cc'd a Administrator at Vox she responded that customer service investigate that was the 3rd September 2022.its the 14th September 2022 NO RESPONSE! then I find out the agent I dealt with had left the company which nobody informed me.the reason enquired was that I don't want any surprises when the next debit order is due
