Very poor services from Walmart Canada

I placed an order online on Walmart Canada on the 1st of February, 2020. Only one of the items arrived some days later, as we speak the remaining item is yet to be delivered. I contacted Walmart customer services via email only to be told the item is from a third party called eCanada. I then contacted eCanada with corresponding emails between us they apologized for the delay and said the item was damaged in transit which I was not made aware only found this out because I complained. Then on the 3rd March, 2020 we both agreed that they can reship the item and they confirmed to me it will take 20 days to be delivered. As we speak the item is yet to be delivered which is not over 30 days. I have not received any word from eCanada, I have also made Walmart Canada aware about this issue and waiting to hear from them. I just don't know why Walmart will have dubious and shady 3rd party service providers on their online sales website and can't do a follow up of not getting things I ordered for, whereas Walmart received the money on behalf on eCanada from me. This absolutely outrageous services from a big brand like Walmart.
