Unable to download order-[protected] invoice.
When downloaded, it is showing black page. Requested to contact customer care. I have contacted cc through email and chat but no solution. They have given 48hrs resolution time. Time has passed over 6days but no progress. I followed up their swiggy support email, but still they are unanswerable to my issue.
