Telkom Internet

I have a 10Gb contract with them. I have used up my data because I'm working from home during the lock down. Bought 5gb + 5gb for R300 yesterday now they gave me 5gb anytime and 5 Gb night time. That wasn't what I wanted and it didn't show it like that where I have topped up. I feel cheated and dissapointed in Telkom for not helping their customers during this tuff time. Im starting to think to cancel my contract!!! I have send email still no response. Really unsatisfied with them.
