bad service no resolved

i went to upgrade my contract for the iphone 11 which was on special at makro crown mines we filled out the paper work n got our phones and new sim cards till date i dont use the sim card the lady at makro Queen who assisted me took out a whole new contract and not upgrade as was requested by me, she said she will cancel the other number n upgrade it but she didnt do such i got a bill from vodacom off R2000 and this was ridiculous, i went to makro they said i should reverse the debit order because Vodacom is wrong. I trusted the MAKRO consultant, Queen to do her job and do it correctly not do it half ass and then leave me with a bill that i am not liable for, I am liable for the new contract which should have just been an upgrade not the old and the upgrade together. contracts was upgraded man years ago and i have never experienced this incompetency from a store prior to this. to top it off Shakir who also works at this Makro made promises he never kept, kept me calling everyday since the begining of November, i was sending emails trying to get this resolved, and he admitted on numerous occasions that it was Queen's mistake and that the store is liable for the outstanding amount as well apologized numerous times for the store creaing such an error. Today I called him and he was so rude asking me what must he do, dont make promises to your customers if you not willing to keep them. this store has caused me unnecessary stress and anxiety as well now the possibility of being blacklisted by vodacom, Vodacom should retract their business from Makro as this is going to cause Vodacom to loose their client base. I should have stuck with CELL C as their service was way better satisfactory than vodacom.
