Bad service

After my last report about Telkom they responded the same day, saying that I will be contacted soon. 2 days later I got an email saying that they tried to call me and there was no answer. I had my phone on me the whole day and did not have any missed calls. The email said please reply to [Email Removed] so I rep**** with my correct number and said please check that you have my correct number. 2 days after that I got the same email so I called myself to make sure nothing was wrong with my phone, everything was working on my side so I sent them my correct number once again. This time with no reply. I still have 20 gigs of Internet that I paid for and I cannot use it. I realy don't want to lose all that money, if they cannot provide the service I just need the money back to use Vodacom instead.
