Bad service McDonald's Montague Gardens

I ordered two Quarter Pounder Meals with cooldrinks via Uber Eats from McDonald's Montague Gardens last night 12/12/2020 Firstly there were no cooldrinks available other than energade which I paid extra for. On arrival of my food neither of the Quarter Pounders had any garnish only a slice of cheese and a teas**** of tomato sauce. I then had to contact another branch to get hold of the Montague Gardens outlet. I spoke to a Thobeka/ Thombeka who apologized and said that they would send me burgers due to their error the following day but that I should call her after 10am on Sunday so that she could arrange it. To my frustration, I have called them over twenty times, the number either rings or goes straight to voicemail. I have left two messages for her to please contact me and it is now 12:30 and nobody has come back to me. I am really angry as its my time and money wasted.
