MTN contracts

Please expose MTN for misleading people do not ever take up mtn contracts because they are misleading us, I have calling mtn from the 22nd of January to cancel the contract, I even lost for words I’m so furious coz I’m transferred from pillar to post and I called within the cooling off period. Now it’s outside of it and nothing has happened. I contracted for 40gb then I was allocated 30gb, their router the battery ode is weak and the network signal is weak you have to constantly carry it with you around the house Yoh please do not fall for this mtn they are ****mers.
