I founded an AI-native software manufacturing company and chose Microsoft's Azure infrastructure expecting reliability from one of the world's largest technology companies. Instead, two small AI fine-tuning jobs produced a documented 1,000× billing-unit discrepancy. Azure reported $74,921.93 in usage, and my bank received attempted Microsoft card authorizations totaling $201,575.78. Thankfully, those authorizations were blocked. Microsoft subsequently suspended my subscription, canceled my $5,000 startup credits, and converted my account to Pay-As-You-Go. Here's the incredible part: I independently investigated the discrepancy, reconciled Microsoft's original billing CSV against its own training-job records, and submitted a nearly 40-page audit packet with the evidence and root-cause analysis. Microsoft's response? Engineering needs another 5–7 business days, after which they'll review the possibility of reinstating my startup credits. To be fair, Microsoft did restore access to my subscription, and Executive Customer Relations has acknowledged the complaint. But the billing discrepancies and startup-credit cancellation remain unresolved. The AI model was trained but apparently, the billing department still needs training. 😭 I'm giving Microsoft two stars because the technology has enormous potential, but reliable billing and accountable customer support are fundamental requirements, not optional features. I hope Microsoft uses this incident to correct the underlying failure and protect other startup founders.
