Vodacom Service

I got a call from Vodacom customer service regarding my data usage , I was spending a lot of money on buying data,almost every third day I would buy 1G of data after and I have a contract with Vodacom which gives me 10g of data ever month but it wasn’t enough because I am always on social , so they called and were concerned of my data usage and asked me if they can increase my data and still pay minimum I can afford ... and I agreed after a thorough explanation and today am happy I don’t have to spend a money in the middle of the month for another Gigs and I can still carry over to the following month...
