Bad service from MTN...I'm disappointed!!

I have a very serious issue with the service received from MTN. I requested my pensioner Mom and my kids a R249 month to month contract for a home WiFi router and on 5 October an amount of R465.87 was deducted as discussed over the phone and agreed to. The amount was supposedly covering the month of October and November (pro-rata for Oct and full amount for Nov). They confirmed that the router will be delivered within 3-8 days after the first deduction but the thing only got delivered today, the 25th Oct. This means money was deducted but we never benefited anything, instead we had to continue buying data every single day for the whole month though money was paid to MTN. Everytime when we follow up, they'd say they don't find the address though they have about 3 stores that I'm aware of (there might be more) around Mmabatho that they could have then delivered it to seeing that they say they can't find the address. That is just a feeble excuse to bad service they offer.

Right now I either want a refund for the month of October or an arrangement to NOT deduct the next month as we've lost money for October without being in possession of the damn thing. It's very unfair to take advantage of old pensioners, always coming with excuses when they call to make follow ups because you know they are understanding and meek. I need this to be resolved ASAP with a fair solution.
