Appalling Customer Aervice

I have been using their services since Sep 2022, they normally deduct from my account on the 1st of each month until tomorrow when they sent me messages at night informing me that my payment was unsuccessful which was strange because I know I have sufficient funds in my account. I then realized the problem could be that I had to change my debit card seeing as it was expiring but the account number is still the same. I have been struggling to get a hold of anyone who can help me to process the payment on the new card since last night, this morning at 5am they disconnected my services and I am stuck here with no wifi. Their agents are not responding either on Whattsapp or the live chat on their Customer Zone, I am so horrified I don't know what to do. This is appalling honestly, this coming from a customer who has never given them problems for over a year and now they can't even attend to my query. Their customer zone is also not user friendly, I cannot even see where my card details are so I can maybe change to the new card or anything. I am horrified and highly disgruntled, I am stuck right now I have no Wifi and no one is attending to me 🤬🤬🤬
