Disappointing manager

I was at polokwane, Limpopo mall today and I have never received a very disappointing service from front desk ( cashier) and the store manager. Last year around May I requested for some magazine charge to be cancelled and they gave me a form to complete, which was done by myself and it was submitted by me at the Foschini store, Limpopo mall. I have visited the store today to make some payment, and I have noticed that the magazine part was not cancelled by the Foschini store. I was requested to give my ID book so they can call the head office to do the cancellation. The call was made and they have said the magazine was cancelled. I have then requested for the proof of cancellation to avoid the previous mistake of leaving the store with no proof of cancellation. The cashier said head office does not issue the proof. I have asked them to send me an email as part of the proof and none of that was done. The cashier opted to call the store manager who have zero customer service, she took the head office call to the back office and came back with zero customer service help. Instead she was telling me that she doesn't not work at the head office nor work at the front desk. I have explained to her my reason of requesting the proof of cancellation. Apparently there is nothing she can do and the head office consultant just do as they please, that's her words. When I was insisting for the matter to be escalated, she then said I am wasting her time as this is her lunch time, the only advice she is giving me is to write an email to head office if am not happy with the response. I am very disappointed and disaggregated by the way she was huddled the matter. I have been a loyal customer for foschini and the TFG group and never in my walk in stores have i came across such arrogant person who does not know customer service. Over and above her store have failed me by not submitting the cancellation form. When I asked where is the form, she responded by saying the papers where thrown away as the store was under renovation. @ the TFG group, can you please intervene in this matter as i am shocked by the level of service we get from your employer's. Can I ask the Foschini head office to look into this matter and address the Limpopo mall (Foschini) stuff and a written apologies from the Limpopo mall. The store manager have failed me as a customer for a simple thing such as proof of cancellation. She has no respect for customers, telling the customer that she is on lunch. Where do I get involved with the lunch while I requested for assistance from her cashier. Because they couldn't handle the matter they called her to intervene. Well she did nothing other than leaving me with disrespectful advises We also work with customers and we respectfully help our customers where we work. If something is above you, then you escalate. I will not leave this to rest as I pay for the account, this will be at all social media platforms if I don't hear anything from the Foschini team
