Pathetic Customer Service

On 06 May 2021, I purchased items from mrp and I was given a slip (hardcopy); the cashier did not ask if I would like for the slip to be emailed to me (mishap 1). Today I go into the store for a cash refund on some of the items, a very arrogant mrp lady tells me to come in at 11am and they will refund me (mishap 2). I go in as advised only to be told that a cash refund is not possible because I do not have a slip – why did you not give me the option for the slip to be emailed to me in the first place? The items to be returned are still in the same condition when purchased with the tags that have the bar codes on them – what is the purpose of bar codes? I then asked for the store manager, the store manager named Lorraine with employee number *** said that there is no way they can assist me. I asked her to refer back to the system and surely they could trace this purchase; I was told that they don’t have any records of purchase – what nonsense is this????? You don’t even want to try to assist….. At first the cashier does not do her job properly and now I should be inconvenienced. I do not want a voucher as I do not plan on buying from any of your stores again after this ********** experience. mrp you messed up from the start, I suggest you sort this out! Asap!!!
