NOT renewing contracts due to POOR service

I've been a very proud Nashua Mobile client UNTILL it was taken over by vodacom themselves. So December I accidently make a payment for my contracts in Nashua's account (after the merge). Since then I cannot get hold of anybody to refund me. The no I get from vodacom's mailbox is full and they don't take calls. I don't understand how you can't have contact with a company but you took their clients over. And you can't retrieve the money so you just cut my line after I sent you all the proof? Then to top it all. I pay you to just get my line on and you have the audacity to tell me I have to wait 3 days for it to be activated cause you don't deal with Capitec. But you are a registered beneficiary on their internet banking??? Everytime you phone I hear a different story. Definitely not upgrading. And both my contract are now due. You service SUX!
