某中学与某服装厂在1999年11月签订了一份服装加工合同。合同规定:由服装厂为某中学加工校服500套,平均每套支付加工费30元,共计15000元;某中学负责提供布料、服装型号和规格;某中学在接到服装厂取货通知后2天内付款,服装厂接到货款后3天内将校服送达某中学。服装厂在规定的时间里完成了服装加工任务并收到货款,依约在第3天将校服送达某中学,可由于该校领导班子正处于调整之中,无人负责接收该批校服。连续一周仍无人出面接受校服。因此服装厂只好将该校服提存。在提存之后,服装厂认为既然某中学领导班子未定,待领导班子确定后再通知某中学来领校服。15天后服装厂才通知某中学领取提存物,某中学在领取提存物时被要求交付15天的保管费用,某中学拒交,认为服装厂未能及时通知学校去取校服,导致校服提存15天,应由服装厂支付提存费用。某中学拒绝支付提存费用的理由有法律依据吗?请依据相关法律规定予以说明。
