Worst Ever Experience Ever

its sad to see how the level of service has dropped. i was in at the vangate mall branch today to report my card ******. upon my arrival i spoke to a young lady whom looks like she was in the department of new accounts, i then approached her and told her id like to have my account blocked. she then responded saying ok shes just busy with someone which was when a gentlemen stepped out of nowhere, she then handed me over to another consultant who at the time was just standing around. this gentlemen however asked me what the problem was and then told me to wait for the lady whom just told me to speak to him about me. after waiting for about 20min whilst listening to these 2 consultants chatting away about personal things the customer finally finished on the device and then i get told about customers that just walked in that had been there before me. at this point aside from already being frustrated i request to speak to the manager for the main reason being in the store the whole time ive been standing around and not once was i asked if i had my id or whatever details is required from me. upon my request to speak to the manager i got addresses with anger and frustration. upon meeting the manager i then attempted to tell her what my issue was and yet again addressed with rudeness, no help just attitude. i understand that me wanting to block my card does not bring any businesses to the company however it is in my experience that these type of issues are addressed with more empathy or atleast by knowledgeable staff, i decided to leave the store and attempt to block the card on my own and decided to ask the manager her name as she nor the other staff assisting me wore any visible form of name tag, she responded with "id rather not tell you my name, it wouldnt matter anyways as nothing will come from it but you can tell them its the store manager", i then asked her name for a second time as and she shrugged it off with a smirk whilst dealing with clients. really unprofessional from a store manager. one would expect a brand this old to have better treatment towards there customers. not sure if i would be reactivating my account now. thanks for a great start to a new month!
