Bad service, no responce, missleading

Vodacom took over Nashua Mobiles Vodacom accounts, I requested that they should join my existing account with Vodacom and my Nashua mobile account onto one account, their customer care told me to send a letter requesting this. I have send them a mail on the 23rd of February 2015, I made a payment at the end of the month to one account witch I requested both accounts should fall under. I then send the proof of payment to there accounts apartment stating that it was for both accounts. Today they send me two accounts stating my old Nashua mobile account is still in arrears, I phoned them twice and cut me off while holding on. this evening they cut my Nashua mobile account.<br> I phoned the customer care department requesting that they sort out the problem immediately. their response was that they cant combine both accounts and I have to phone their accounts department tomorrow to sort out the problem. I asked for a manager and I had to wait 10minutes because Chamelle Wepner was on a tea break. and when she eventually came to the phone she had the same response that what ever their call centre told me before cant be done and I have to phone their accounts department.
