Money Saver Credit card *****ulently created under my name

Last year I discovered that there was a Sanlam money saver credit card that was *****ulently created under my name. I have never transacted with Sanlam for anything nor have I ever had or app**** for a credit card with any service provider. After discovering about this money saver credit card I called Sanlam and I was given a dispute declaration form which I filled in, signed and emailed back on the 14th of December 2024 till this day I haven't received any feedback. I have called countless times for assistance, the last follow-up email I sent was on the 24th of March 2025 and the response was I will be contacted as soon as the investigation has begun. It has been 4 months and I haven't received any feedback and my credit record which I have worked so hard for is negatively affected.
