Use of company property

I am being charged by my company for improper use of company property for "Sharing"loads from the company mobile phone to my personal number. I thought at first it was ok since i pay for it when the bill comes. Our company does not provide loads for its employees,so when i do n0t have any m0ney to purchase a prepaid load,i share the company's load to my cellphone and when the bill arrives,i pay for it instantly. I use the load for work related cncerns since my job is involved in Operati0ns,a part of it also for pers0nal use. i have done it thrice,the first time i thought it was ok(i never receivd any warning or mem0). the sec0nd i already received a mem0 and an incident violati0n report. Is it fair that they charge me with such,since there was never any formal directive that sharing loads is a violati0n of the company rules? i pay for it when the bill comes,frm my own pocket.they never provide company loads for employees although im an officer and i use it for work also.

IMY, its a company property and you should have not use for personal number unless you are authorized by the company.
Regardless if you are paying it. The issue here is it was not directed to use it for personal who knows and who can defend that
those celfone loads were for operation/company use or purpose?

not safe to be so presumptious, even if you used it for business purposes, something you would have to prove. considering there's a mobile phone issued by the company, then any use of your personal use will be presumed to be for personal use.

i recommend you just apologize and hopefully they will not be so harsh.
