Sour taste

Very disappointed in their customer service. I had had an issue with a product i had purchased from their factory shop in PE. i complained and i was told to return the product to the factory, of which i did, just to be given old things AGAIN. I complained on 19 July 2019,i was told that within 72 working hours i will be contacted .10 Days later i contacted them, because i wanted feedback regarding my unpleasant products. I was then told i will be reimbursed with a voucher for my troubles. That never happened, in fact i contacted them on the 19/08/2019 and queried once again to which i was told i would be called back. On the 27/08/2019,i was called regarding my query,whereby the lady nicely informed me that i will NOT be reimbursed by parmalat for anything as i would have to return to the factory shop to return the product as they do not reimburse factory purchases.Now why did it have to take them almost 2 months to tell them this, was i suppose to sit with off milk in my house until they decided it was fit to contact me. Why couldn't they tell me that to begin with, And why let your customer consultant tell me that i would get a voucher. Would you have batted your eyes at my off milk if it made my 14 month old daughter ill, cause she drinks the milk not me. At the end of the day its simple, whether it was bought at the factory or in a spar, it is still YOUR PRODUCT AND YOUR NAME. I am NOT a happy client. If this is the kind of service one gets for being a loyal client for many years then i would rather go elsewhere.
