Courier was meant to collect package on a Friday. They claimed to have been at apartment however they never called or buzzed and I was unaware they arrived. I called customer service on the Monday to see what happened and they were very rude on the phone and blamed me when I explained what happened. They should be taking the customers side and not assuming it was my fault, they automatically assume I was at fault, not impressed with attitude on phone.
