Strugling to get my deposit for helium rental back

<p>For more than a month now I have been struggling to get my deposit back for renting helium from Afrox. If you phone customer service it takes ages to get trough and in the end of the day I have used more than R100 airtime to try and get my deposit back. Finally got a e-mail stating the money will be in my account on the 21st of April. 21 April came and it also left but no deposit has been received up to date. Really dissapointed and will take my business elswhere in the future.</p>
