Poor service

After 19 years of being a client of Vodacom I must say the service has gone from good to bad in the last 2 years. Last year when I wanted to upgrade I hear my account is in a rears so I had to hand in all my prove of payment. (O we are sorry the fault is on Vodacom side) that was 3 days later. This year they say the system say no finance it is day 7 today and still they can't sort it out even your update center now say that I am not due for a upgrade what a load of **** in the beginning of the week I called them and they told me that if my profile is sorted they can help me with the upgrade so what is going on at Vodacom. The Vodacom I went to cant sort it out the say it must be done from head office side
