Vodacom Poor Service

What poor poor service from Vodacom!! Getting put through to accounts and customer service and nobody can help!! Paid up all our accounts and nobody can assist with a paid up letter?? We're told we can receive the letter in 24 hours after it has benn settled but now only told end of the month (1 Feb). Is in the process a buying a property and the banks need the document, nobody even willing to assist us with a letter stating it has been paid?? How is this for service delivery. Couldn't even assist with a letter on the one active number had to cancel even the internet line just to be in a position to obtain the letter. How pathetic? Will be moving to another service provider and will not recommend Vodacom to anyone!!!
