Buyandget poor service

Good day

I bought 2 samsung products in November 2017 from the Samsung store .Firstly I had to continuously call the store to find out when my products would be delivered ,I only reieved delivery in December

I choose to purchase the items mainly for the buy and get promotion as I was deciding between the lg and Samsung products.

It has been more then 10 days and I have called the buy and get customer care over 4 times to get feedback twice i was told that a consultant will contact me to assist .The first time I called in The consultant told me I will receive my pin to redeem the rewards on the day of the call however nothing was sent through

No consultant there after was able to assist

I have just been told to be patient ,All i want is feedback and an expected date to be able to receive the rewards.For a company that makes state of the art products .I am not sure why this is such a hard request
