Poor service😡😡

I am extremely disappointed and frustrated with the service I got at Fair Price at the store they charged me for a Delivery. The drivers at Fair price up ****ed because they demand more money from me after I have paid for Delivery. Please do something about this because its not fair. You guys are cheating people. I paid for Delivery. When i call the head office no one is picking up.😡😡😡😡
