Slow or NO Response to Queries

I am very disappointed with Mobicred at the moment. My debit orders have successfully gone off every month for the past 2 years that I have been with them (this month included) - now all of a sudden I get the error that my account requires verification, whenever I try to make a purchase. It has been far over 24 hours and after several Whatsapp messages, multiple emails and a long wasted attempt to get through to their call centre, I have not even received as much as a call or a response that they are looking into it. All I get is the automatic response that gets spat out by their system when they get an email. Nobody wants to have their time wasted this time of year when gift shopping and facing the disappointment of an unreliable credit provider, which now results in massive delays and late deliveries. They are happy to take my money and spam me with marketing emails, but fail to provide a proper service when I need it the most. Yes, this time of year is busy, but they should be accomodating for the increased workload and ensuring that they can handle queries, instead of litterally making their loyal clients pay for it. No point sending me bunches of emails every day about what and where I should be buying with Mobicred, when my account is physically not working.
