Bad service

Last week I booked for a parcel to be shipped,when I got to the locker ,pin doesn’t exist,contacted them on their WhatsApp took ages to get a response,after sometime being told to keep on putting the pin because it’s not tracking on their side,then I was told I have to book again & I won’t be refunded for the expired pin,I did as I couldn’t tell my client stories,,,,at the same time I purchased stuff that going to be shipped to me by Pudo,,,no Pin no communication up until I asked my seller to do follow up she told me the same story of expired PIN,then I asked her to cancel my order,then left right center calls from them even wanting to come & drop the parcel at my doorstep & yet imy order was Locker to Locker,,,can someone explain to me how do they treat their customers & it’s not the first time they treat me in this manner,i REGRET the day I chose to overlook the REVIEWS before signing up with them,,,95% of them are of bad service
