Vumatel sales department would not allocate my payments even after providing them with proof of payments

Sales department of Vumatel is the worst I've ever seen. I've been without internet since the 24th November 2024 simply because they're not allocating my payment. I called their support line so many times and each time I'm told the issues has been escalated to sales. I made 2 payments after my ISP has suspended my services, but to date I'm still without internet. I've shared proof payments and everything they wanted but they still can't allocate my payments so I can have internet. What is this sales department doing entlek?
