Mobile WiFi LTE data top up

Current reference number ***1<br> I have a contract with Telkom Mobile for 10GB data per month. For the past 3 months I have run out and have topped up with a 5GB data bundle, purchasing it via eft. The data is \used up\" within 24 hours. If I then attempt to purchase a second bundle, it doesn't even go through, and it takes up to a week for anyone to get back to me, even with proof of purchase supp****. On the 22nd March, I again purchased a 5GB bundle. When it finally came through, I simply checked that it was on at around 14h30 and checked my email. I was informed later by the technical department, that by 15h00 3GB was gone, and by 17h30 the rest was depleted. <br> This is impossible and I do not believe that the correct amount of data is being loaded. It is impossible to actually get hold of anyone to talk to either at the Telkom Branch or via the call centre. <br> I find this very stressful, as I am unable to work, and unable to resolve the issue. My contract is up in a couple of months and I am not sure if I want to sign up for more stress, and no service."
