Poor service to long standing customer...

Due to being retrenched my Vodacom account fell into arrears, however when I secured employment I made an arrangement with Vodacom to settle the arrears so as to keep my services. As a client of Vodacom for approx 20 years one would expect some proper customer service from Vodacom but I made one payment and the lady who assisted me never let me hear from her again. I need Vodacom to contact me so that we can conclude an arrangement as I need to be able to use my cellular service. Certainly long standing customers are important to Vodacom??? My cell number on which the problem exists is *** and I can be contacted on ***
