Data depleted before being used

I bought an Lte data for R149. 00 on the 15th of May 2020 which 10gig is for day and 10gig is for night surfing. I tried connecting and it was giving an error and i couldnt access my whatsapp. From that day when i check it, it was only showing balance for night surf. 3 days passed and i could only access my whatsapp only from 12 midnight to 7am. I then charted with Londiwe Sokhela who said my data is depleted. She sent me summary of my connections and it wasnt opening because it is *******ed. I rep**** to her email but she never responded. I sent another chat and was speaking to Paticia Shamase who did the same thing. I asked her to check when was the last day i recharged and she gave me the date. I then said she must check the sites that i opened to finish my data and she says she is unable to check. My problem is my data was depleted before being used. I mean 10gigs of data is a lot. I bought so that all of us in the house can connect especially during the lockdown. HELLOPETER please help me, i need my 10gigs of data back. Thanks
