***** online service

I ordered a an Aldo bag from an online store called Zando a few weeks ago today I got an email coming from Zando telling me my parcel was delivered but I wasn't the one who received the parcel. I called their customer service and the lady who assisted me also said "mam your parcel was delivered this afternoon" and I told her no it wasn't because I was at home and I didn't sign off anything. She put me on hold so she could find out further and she found out that the courier company lost my parcel ? so my query is why wasn't I informed in time about this problem and what were they gonna do about replacing my package etc but instead you guy's sent me an email informing me that they already delivered my parcel. The lady further tried to explain and I told her I was running out of airtime and can she call me back so we can sort this out and she agreed. At this moment no one has made contact with me, they inconveniencing me because I've been waiting for the parcel for a week now. Its the first time I experience such ****py service and the person who had recommended Zando to me spoke all positives about them but now I'm here with no bag
