Natradale Vitamin B is Dangerous

I have purchased Natrodale B Complex High Potency product last year. A product of Ad**** Ingram. Me and my husband drank this Vit B a few times. I don't know what is in, but it pose serious health risks. It gave us both heart palpitations and I experiences epileptic fit-like symptoms. I emailed Ad**** and they are not taking responsibility. Seems like they're not interested.

The serial number is ********** 584240.

I feel I have wasted my money on this expensive supplement and put myself and my husband at risk.
