Beyond appalling service!!!!!

This is absolutely the worst courier company!!!!. If there was zero rating, I would give them that. They have my parcel allocated to the wrong address. They then send me a link stating that they cannot locate postal code. I update the link to my correct address which apparently did not update their system. Escalated the matter when they later tell me they can't deliver the parcel & that their system didn't update and pretend as if they assisting me after up and down emails the entire day yesterday and that they have changed my address, Icall today & they still have the incorrect address after me receiving an email from them that the address is changed. Now they say I must contact the supplier. I am actually so horrified with this service. Buffalo, you should actually be shut down!!!! Your service is beyond appalling!!!!
