ONE DEAL A DAY IS A ****!!!!!

I’m really disappointed with One Deal A Day service. I bought a 2 in 1 portable air pump and jump starter and it was not working. I bought this item in December and sent my 1st complaint for return and was only responded to in January. I then followed all their instructions to return the product. I’ve been trying to contact them regarding my exchange or refund and was informed that their courier lost the package and now they are ignoring me for my refund. I sent a lot of messages to no avail. I’m never buying anything from them again they are a ****!!!!😡
