Call centre Vodacom sucks

I 0honed Vodacom in the week to ask a paid up letter as I have no contract with me, the advisor that helped said i will get it in 24 hours, after the call i received a sms saying my PUK number can be changed really now. Then i called 3 days later again asking why I received a PuK query when i requested a paid up letter as they reflect on my ITC report but i finishes my contract 4 years ago, the advisor this times yawns on the call then when i ask her did you juat yawn, she then Drops the call after waiting in a long call line. This is bladdy weak service from there call centre will never do business with them again. This has happened numerous of times where you call the call centre and get the worst service what about customer satisfaction. Wonder if they even do call coaching with staff or any training or listen into calls.
