A discounted price!

I called Pathcare on Friday, 6th October to query a credit that my daughter had advised me of and spoke with Michelle Mhlontlo who told me that the credit could not be used for my test as my daughter had the credit.

I then called the Accounts Department in Cape Town and spoke with a gentleman In the pricing department who told me that the test would cost R313.90 with the senior citizen discount. went to the branch in Rosmead Avenue and produced the credit (which was actually in my name) and was told by Ms Michelle Mhlontlo that the price for the test was R624.90. I did not want to argue so I paid the difference of the price she gave me less the credit. All Pathcare's calls are recorded and I would like an explanation for the discrepancy
