Bad service

Got 4 contracts with mtn I pay close to 1200 a month yet getting service from them is pathetic Went to tbe store called customer service even sent fb messages on messenger but not one response All i asked was for my other numbers to data share to my main number Also tbe dropped calls n signal losses and no compensation Data gets used to fast yet i do the same amout of stuff with other networks and tbe data last longer I hope some senior reads these complaints becuase i have call recordings and proof of how many times im asking for assistance but nothing is being done
