Terrible assistance and no feedback.

I received my package last week Friday 4th of Dec 2020 which I ordered on the 29 Nov 2020, I noticed that my order was incomplete, I ordered child mer**** PJ set but I only received the shirt and not the pants, so on Monday 7th of Dec 2020 I contacted the online costumer service department which I waited a long time for someone to answer the phone, a lady picked up and stated that she needs to contact the warehouse as the order came from them, after waiting 21 min I was cut off. I phoned again and this time the phone was answered faster, I spoke to a guy and he stated that the lady I spoke emailed to warehouse and when they receive feedback they will contact me. I have sent a complaint email to the ***, stating that I want them to send me the pants as soon as possible as I already waited a week or they need to discount half of the price on my account. Today is the 09th of Dec 2020 and still no feedback by phone or by email. I am very disappointing and I never had such issues with TFG.
