pathetic service

I have been trying to query my account by phoning vodacom on *** for the past 2 weeks now and no one can help. The first lady Norma kept on putting me on hold for about 3 times for more than 5 minutes at a time. When I asked what her surname is, she then cut the call. they keep on saying they are transferring me to the accounts department but I end up at the same place. I am sick of trying to contact them. I am recieiving smses to say my account is in arreas when I made a payment on the 25/1/2016 so all I need to know what this arrear payment is for. This is pathetic service from vodacom but it is not the first time as it took 3 weeks for them to upgrade my account due my my number being transaferred to a new system that I was not aware of. please can someone contact me from vodacom that can actually assist me.
