Where's my money and router!!!!!

I'm extremely disappointed with MTN. I was accepted on the 24th April for a month to month deal - R249.00. Anyway they required me to pay R307.10 on that day (24th) and sent me a payment link to make payment, which I never did, as I hadn't received my salary yet. Anyway a gentleman called me on Tuesday - 02 May to say that I must make the payment of R307.10, so he then sent the link again to me, but unfortunately my online limit was R300.00 at the time, so payment was rejected. I saw they provided an MTN Standard and FNB Bank details, so because I couldn't use the payment link twice I paid into the MTN FNB Account, with my reference provided. I received an email from customer care now saying that they can not pick up my payment with the reference I gave. BUT I attached a Proof of payment to the email. Now I want to know where my Router and R307.10 is sitting. Everyday that goes by is a day that I am missing out on data.

And to get hold of someone is IMPOSSIBLE. Helpful my ass.
