8 months paying for 10mb line and getting 4mb line

We pay R800 pm for Telkom ADSL line at home to have a 10meg line, this was installed in May 2015 and since then we have only had a 4meg line but we still pay for the 10meg line. We were also suppose to receive a DSTV Explorer but never received one as no stock available ever.<br> <br> We want this to be sorted out immediately and receive compansation for the variance paid for the last 8 months.<br> <br> This is completely a waste of money to have something less than half of what you are paying for.
