Dissapointed

Good day I have been paying for a 4mb speed on my ADSL line for more than 2 years. In this week, I have been informed that my area never accommodated for 4mb lines only 2mb. I want a refund for all the additional line speed charges that I have incurred. The only reason I found out that my area was on 2mb is when I decided calling in to upgrade my deal to a higher package that was advertised. R605 which includes uncapped and anytime extra on my voice line. The sales team now informs me that the system will not allow for this change as my area can only accommodate for a 2mb. The billing dispute has still not been resolved reference ********** 0. Now Telkom what can you offer me or would you want to lose a long standing customer because of your errors. I want a call back from a Manager explaining why I was never informed about my area's speed, why I was overcharged for a 4mb, why can't I get the deal for R605 and when will my billing dispute and credits be finalized.
