Bad service

I am an unsatisfied customer again with this telecommunication network.

On the first of each month I receive my data allowance of 2GB daytime and 2GB nighttime data. Unfortunately on the 2nd of September my day time data had already been depleted within less than 24hours and I did not understand how as I have monitored my data usage. I called the service provider and it was still unclear as the consultants have no access to a detailed data usage log, however I was told one of the social media sites that was a contribution to this depletion was 'Facebook' and I have not had an account nor alternative used the site for >10 years; and WhatsApp (which I account for). Another concern is that my nighttime data has not depleted and my usage and sites I enter during this period are no different to the ones I had used during the period in which my 2GB daytime plan depleted.

Moreover, when I went into the Cell C app I recognised two devices connected to the router and yet there was no other device connected at the time from myself or individuals around me and again the consultant could not verify the second device.

I understand the training to the call centre consultants is relatively limited and disadvantageous to the paying customer but no alternative assistance was rendered to me at that moment but a nere email to the customer service centre - with little information to the response time, might I add.

May I please request an investigation to this matter with descriptive answers as to my usage of data. I do not have Facebook; WhatsApp in less than 12hours does not claim a substantial amount of data and any other site used for that matter.
