MTN GREAT speeds - helping a small town succeed, much appreciated!

THANKS MTN - Somerset East really appreciates that you have installed a 4G tower in our town. :) This is an amazing enhancement for us! As we all were struggling tremendously with internet speeds. Now we FINALLY have a very high speed internet connectivity with you. Much appreciated MTN customer. Currently I have a cellphone contract with you, but we use ADSL which is only 4mbps...But we use 80gb more or less per month and we are considering to upgrade to MTN 75gb(anytime) promotion rather, but we actually need 100gb contract, but it seems like the highest per month is 75gb with the promotion... Is there no way to offer a 100gb one at least? As we really would love to cancel our Telkom and move over, but I don't think we have Fixed LTE in our area, only normal LTE, so we need that on the normal LTE??

But yes, thanks, much appreciated :)
