MTN Not to be trusted

I was contacted by MTN to subscribe to a Data contract. They informed me that I would get a modem with 300mbs unlimited and that the modem will have battery backup. The modem is a ZTE MF286C1 Cat 6 4x4 Mimo CPe modem They ****. The modem does not have a battery backup. I als did not get 300mbs as they claimed. Do not believe a word that they saying. Its sad to say the least what companies would do for money.
