MTN contracts are **** (Mondo)

MTN agents they always sell lies. I had a contract with them from June 2021 until June 2023. The guy called me and said my contract will be renewed with same benefits(14 gig day and 14 gig Night datas) to my surprise they only gave me (4gig day and 4 gig night).. I called them about this but they never rectified their lies.
