Vodacom Bad Customer Service

Went to Vodacom for U in Pearce Road yesterday to apply for a new contract for my daughter. There was an issue as Credit Bureau had negative comments about me. Came home, called them and it was because I paid Edgars and Miladys late this month. (We moved house at the end of November and had no internet for 10 days) The amounts that Credit Bureau were giving me negative comments for were R365.00 and R120.00. Vodacom asked for Proof of payment to Edgars and Miladys so I went home and printed them. After waiting in the queue to see our helpful lady, Joyce, she was then told that she needed 3 months bank statements. Went off and got those and about an hour later got back to Joyce. She was then told the application was in the queue and would take between 1 and 3 hours to be approved. Today after much to and froing Joyce tells me that that they need me to go into the stores to get letters to prove that I have made payment. Is this the way to treat a loyal client who doesn't just have one contract with Vodacom??????
