MWEB LTE Service or Lack Thereof

I received my LTE router on the 30th of July without any SIM card and since then I have tried to contact MWEB to ask them where the SIM card is seeing as my account is active with them.

I have logged several queries and received no response. When I opened my email today I saw that they have already sent me an invoice and the amount was more than the contract stipulated. So not only did they not send me the CELL C SIM card they also billed me for a service that I did not receive.

If this is the way you treat your first time clients I guess you don't have any longstanding one's left.
