Very poor services

I placed an order online and paid for it on the 25th of April 2021. I have not received any feedback. The order said 7 to 15 days and from day 8 you will start receiving feedback on your product. I have tried to send an email however it does not go through. I tried calling numerous times on the number provided tried all 3 options but does not go though it just said the person at ext. Is not available. Can someone call me urgently or respond to my email.
