give me service before you bill me!!!

On 8may I upgraded to a blackberry passport and was promised delivery by 12may,after numerous annoying calls I only recv it 18may,I phoned the office 19may to advise an error on the device,(brand new) I was told it will be collected from me same day or next day, its now the 3rd day after and still sitting with the device in my office, it took ages for delivery, taking wayyyy too long to collect,and who knows how long ill wait to get it back again..in the meantime, my bill has already been adjusted with the charges!!! 8 yrs I've been with vodacom, and never had such pathetic service... Upgrade on your service delivery before you make negative changes to my bill, I will not pay for this kind of service, I'm your customer, relook at your policies regarding customer service.. Come on man!! I have been patient enough!!! Do something worth my money!!
