SONIC Drive-In locations in Memphis, TN

Manager: Kaln 3-Bad Experiences within 2-3wks time! This is extremely unacceptable & ridiculus. My last experience was on 06/16/15 after 8p.m. I ordered an Oreo Cheesecake MasterShake. This Was my favorite shake until I ordered it at this location recently. I thought I had the wrong shake, because it tasted like chocolate & I couldn't taste cookies, nor did it have the graham cracker pieces on top. The Mgr. Kaln fixed another one & brought it to me. She said she was standing there for me to check before she left..I poked my straw throughout the shake. There were No Cookie Pieces & it was completely smooth. I WAS VERY UNHAPPY. I asked Kaln where are the cookie chunks? She said, THERE ISN'T ANY, BECAUSE SHE'S SUPPOSE TO BLEND IT ALL TOGETHER!!! I COULDN'T TASTE ANY OREOS'. I PAID XTRA FOR A CHOCOLATE SHAKE.THE SHAKE WASN'T SWEET BECAUSE OF THE VANILLA FLAVOR SHE ADDED IN! LASTLY, I WAS OVER CHARGED. THE NEW MENUS SHOWS (L) $6.99 FOR THE MASTERSHAKES, INCLUDING OREO CHEESECAKE. AFTER 8 HALF PRICE. ON TOP OF THE HAL, I WAS CHARGED $.30 FOR OREOS'-i understood that still totaled half. I WAS ALSO CHARGED AN ADDITIONAL $.20 FOR VANILLA FLAVOR, SINCE WHEN THIS START HAPPENING? WHO ADDS VANILLA FLAVOR ON VANILLA ICECREAM???IT'S NOT NEEDED. I was Very UPSET. I called the Southaven, MS. location to verify that they're suppose to operate the same way. When I visit the Southaven location on Airways & Goodman Rd, The service is always great! Great attitudes! Order is Always correct! & I have Cookies in my Milkshake!! I shouldn't have to drive 15 miles away from my home & there's one about 3min. from me. The lady I spoke with did confirm that I shouldn't have been charged addl' $.20 for vanilla. I just may go back to keep my tickets & inform the News Station about this..Because that's Too Many People getting Overcharged Per the Menu's Prices Everyday throughout the day over time!! Now, I know prior to the new menus flavor(s) appeared as an add-on(based on the register) but you still paid what it showed you the price was. Now, the New Menu's plainly states what's included...I was told that it's another location that does that. I would suggest that All Sonics in Memphis be Audited if this doesn't get Corrected Soon, Internally!! The Worst Sonic Visit Ever!!! My Oreo Cheesecake Shake from this E.Shelby Dr. location did not look like your photo I added. Please followup!
