Rude Attitude and Completely Unwilling to Assist

I am assisting my husband with an account that is handled by MDB Inc. With this comes a whole lot of issues and complaints. However, we all know how these consultants harass us, so it's needless to complain about the amount of times they just put the phone down in my ear while I am trying to get more info in order for me to pay the account etc.

So I finally managed to talk to a consultant, Themba, who gave me the banking details, amount and reference to use on the proof of payment. Then I sent the payment to **********

So I thought, happiness, we are finally rid of the rude consultants who phone and refuse to give info. Not the case however!!!!! I sent the proof of payment from my business email address. Now I have consultants phoning me on my BUSINESS cell phone, looking for my husband, when I tell them, like I have told them EVERY SINGLE PHONE CALL, he is in Zambia and what the call is about they say personal. So I ask them if they are phoning from MDB Inc and is it with regards to his Virgin Active account? They answer yes. Earlier I told the lady that I have made payment on Wednesday already and the proof as sent to above mentioned email. She put the phone down AGAIN!!!

So please help me, where can I send this proof of payment to and how do these consultants get my telephone number, if thy did not read my mail containing the proof of payment??????

The harassment and rude attitudes are now getting out of hand!
