Game Mall of the South lie to their clients.

Game Mall of the South lie to their clients. I bought a vacuum cleaner in July 2019 and on 02 October 2019 returned it for an exchange or for them to send it for repairs, however I did not have the slip anymore but had the proof of payment and the purchase date. They advised me that they needed to request for the slip at head office and they will call me back for further information. It is two weeks later and I am still waiting for them to call me while the vacuum cleaner is not functional.
