Dadta Bundles a MESS

I have 2 x 2G Data bundles at Vodacom..on two separate accounts. <br> 1. On the one that starts with 082 I had a balance of 4.3G as at end of June 2015...1.64G expired 30.6.15 and a further 2G was loaded on 1.7.15..however my balance now reflects only 2G due to expire 31.7.15...what happened to the rest of my data and normally it loads to expire in 60 days!<br> This particular account has been a HUGE mess ever since it came over from Nashua Cell...I have gone into your Mimosa Branch twice to try to sort it out...3.Feb and 13 Apr..spoke to Donavan on both occasions and he promised to get back to me...STILL WAITING FOR THAT CALL!!!<br> 2. On the one that starts with 072, no data at all was loaded 1.7.15, even though my account is up to date and I pay for 2G to be loaded every month....when I phoned the branch I was told just sorry there is a problem on the 072 numbers...really how does this solve my problem???
