Very Bad Customer Service

Pick 'n Pay Hyper Brackenfell advertised dog food last month around 17th July 2020, 15kg Pick n pay brand when I got to the store they didn't have any stock but yet it was advertised in their pamflet, I then went to the information counter to enquire about the dog food and was told the store didn't receive any dog food yet they still waiting on it to come, I must leave my name and number there they will contact me as soon as it arrives. Till today 14th August 2020 they never contacted me, I have been struggling to contact them on numerous occasions but didn't come right ether they don't pick up the phone or when they pick up it's the same story they don't have stock yet they going to contact me, Monday spoke to an employee that gave me her cell phone number and told me she will personally contact me Thursday or Friday to let me know if the stock arrived today I'm contacting her and she is not answering my calls I even called Pick n pay customer care and explained my situation with them and they said they will contact the store and get back to me but also didn't keep to their word, this is really unacceptable and very unprofessional of them to have such bad customer service.
