TERRIBLE CUSTOMER SERVICE

After buying a bottle of Nestle Nescafe Coffee and finding small pieces of plastic inside. I had sent an email to consumer services. they then responded and told me they would come and fetch the bottle from me and compensate me with a voucher, which I had only received a few weeks after they had collected the coffee. I have been to 3 different pick n pay stores to use my voucher and it does not work.

have now been trying for nearly a week to get hold of anyone at Nestle. The Landline number does not work and the other you sit on hold for 10min then the phone cuts off. They dont respond to my whatsapps or my emails. this is TERRIBLE CUSTOMER SERVICE
