Regretting

I regret the day they came to my workplace and I singed up for a laptop deal. I later lost the SIM card and as was asked to pay 150.00 to get a replacement SIM card, I have not received it till this day. My employer still makes payments to them even Africa the contract has ended I have been to HR a number of times and I am advised to contact Numobile and when I contact them Numobile says they are not dealing with my company anymore
