Always use interparcel and have done for about 5 years. 95% of time I go for UPS option as always seems to be delivered next day. Only issues are and I point out this has only happened 2 or 3 times is when you have to deal with customer services, for example when a parcel has not been picked up when it should have. Twice I have been penalised by my customer for late delivery because a parcel has not been picked up via Interparcel. Speaking with customer services about these issues at the time I found 1 particular girl so rude and with a terrible 'well that's tough and your problem attitude' I was left speechless. There was no compensation offered which therr should have been or even an apology of any type. With all that said I will continue to use.
