Poor Quality Packing from the biggest soda producer in the world Coca Cola

Purchased a returnable 500ml Coke, opened it up took a sip, closed it. tasted something weird and looked again and saw that the top rim is all cracked and i have swallowed some wonderful little pieces of glasses, opened the bottle and the whole rim fell off, took it back to the store i bought if from, did nothing but said oh look they have a bunch more just like that, i then filled in the online form and sent a message on the coca cola site direct, have not received any response regarding this, it is a serious health hazard and points to very poor quality control, i will probably be ****ping little pieces of glass in the coming days and hoping no serious harm is caused to my stomach due to this, among whatever other complications can arise from this, i am sure they will only send me an "oh we are so sorry this happened to you, we pride ourselves in customer relationship and top quality products ect ect" which does nothing to rectify the matter.
