Worst Service

Good day, I had a bad customer service from Clicks Park Meadows, i went there with the intentions of buying a peanut snack, on the shelf price tag was R15,99 when i got to the till to a cashier by the name of Thabiso it scanned R29.99 i told him its the wrong price he sent the merchandiser to check he found the very same price and told me its sitting on the wrong place,i told both of them its not my fault he called the manager who did not take my story he went to the place where it and did not find the price because the merchandiser has already removed,i waited there with no communication from the manager he just stood there i asked the cashier who was very rude & arrogant whats the way forward he said he doesnt know the management will decide with an attitude, the other thing i want to raise when i was walking to the till the cashier(Thabiso) & the merchandiser were gossiping about the customers that were there before me not knowing that I even know them, I told him I'm gonna tell the ladies he was not bothered also address the manager(with beard) to stop this language of his he is using to the customer its very annoying he must just do a simple greeting to a customer not that language he uses we not interested in his dictionary English.
