eft payments made & confirmed not allocated to acc

Three payments made via EFT's and pop's emailed to [Email Removed] in to branch and a salesman helped me..he went onto my account and confirmed that payments had been received but not allocated to my account. He suggested I confirm with my bank..went to Standard Bank Northgate Branch who confirmed that the payments had not been returned. No one else was able to help me at Vodacom Northgate..I am a senior citizen and am unable to go to Vodacom head office in Midrand to sort this out. I also spoke to Customer Care who also couldn't help me...they actually suggested I go to the branch at Northgate. Before these incidents I had been so frustrated with the incompetence that I had asked Vodacom telephonically to cancel my contract..the person who I spoke to didn't even try to do anything to try to help me...just asked me what date would I like to cancel. (There are two contracts that I pay for)..In addition the monthly premiums have also gone up..not by much but they are signed contract...I have no idea what to do...they are ***********, uncaring and unwilling to help...with two exceptions whose names I have noted...excellent customer skills...willing to assist....need help plse
