BRANCH MANGER WHO TOLD ME TO ESCALATE IF I WANT

on the 26/02/2016 went to purchase items at picknpay and when i did not find the item a very friendly manger named madoda offered me a rain check but due to previous experience concerning the rain checks i refused and he called branch manager to assist but the attitude i got from the manager was shocking as he offered me the rain check and when i refused he told that the is nothing he can do and if i feel escalating the issue will help by all means as that was his offer and if i refuse i can sort myself out and when asked more questions relating to picnpay not having stock he refused to answer and he said he refuses to answer because i will probe more if he should give answers i spent an hour with him and i ended up not buying anything because of the atraeatment i received from the manager he was dictating to me to accept what he is offering if not i can sort myself out , he was rude and arrogant that at one point he told me i was wasting his time because if i do not want the rain check the is nothing else he will offer i wasted my time and he did not care as he exact word were \ if i want o escalate go ahead and it is your own opinion that i do not want to help \"no customer skills"
