Poor client service

I have sent and email 3 consecutive weeks to motorvaps notifying them of my termination of contract, even today I have not received a single confirmation of my cancellation, Their call center takes about an hour to answer my calls, The only option I have is to cancel the debit order through my bank should it go through Below are my ticket numbers: Ticket No. 23613 Ticket No. 21195 Ticket No. 18852
