We buy cars Midstream Branch Poor Service!!

Hello admin I am very displeased with the service i got from we buy cars midstream, i bought a car from them in November 2018 last year, i was promised to recieve my car license disk and plate number around December 2018, since the day i bought the car after finance has cleared, i received no communication from them regarding my plates and disk, my sales person has been moved to a different branch n stopped all communication with me, i have been back forth with the lady in charge of license and registrations in the midstream branch n everytime i went there, there was a different issue, 1st i gave them the wrong address, next issue was i had to pay for my own roadworthy testing even after it was included in the overall payment of my purchase of the car! They blammed me for giving them the wrong address meaning thats they had a delay with the delivery which was not true because firstly i they waited till 1 march 2019 to tell me the wrong address meanwhile they have been telling me, there is an issue with licensing dpt cos of december vacation! They kept on giving me permits, i have upto 6 permits now and till today i have not received my disks and license disk, the service is very poor in if i could i would return the car and go find better service elsewhere! Im so disappointed im tired of fighting them! Last friday 1 march 2019 they told me they submitted my new address and the results from roadworthy testing they said i should come today 4 march 2019 to collect but yet nothing! More excuses! I am really sick and tired of their service to date, they dont care about their costumers after payment has been done! Dont be another victim people!
