Lost Belongings

on the 5Th of January i went to buy breakfast at Pick n pay Mafikeng, i left my phone in the counter, when i went back to request assistance on recovering my cellphone, Agisanang told me that they wont be able to assist me, is not their responsibility, if a client left anything in the counter. it is none of their business, he was very rude he even told me the manager is on holidays, even though he was in the store they wouldn't assist me with the footage. the cellphone that i lost is a departmental phone i really need it back i also kept the receipt to show the time i bought breakfast.. Your assistance in this will be highly appreciated.
