Impossible to get query resolved

MTN did not upgrade my contracts but rather issued 2 new contracts, selling under false pretenses. After being sent from pillar to post and speaking to several employees, nobody seems to know how to correct this. Eventually had to go to a store to hand in the sim cards. And then phone AGAIN for a reference number. My query has been logged on 25 May 2020 and still have not been resolved. MTN does not know the meaning of Treating Customers Fairly. Why are they making it impossible to resolve a query? Or to cancel a contract they *******ly sold? I will never recommend MTN to anybody and will cancel all my contracts with them when they are at the end of term. MTN will now lose a loyal client you had for many years.
