Putred customer service

Had my worst ever customer experience with this company Rochester. placed and paid for my order on the 05 August 2020. was told max waiting period for delivery is 15 days. after waiting the 15 days I started enquiring about my delivery for a week with the online contact centre. I laid 2 complaints and was advised that someone will call me to assist me. Still have not received a call till today. then on the 26 August 2020 I received an sms that my order will be delivered on the 28th August, still nothing was delivered, I then called Rochester again and they advise that their is not stock of my order. I told them to call me to give me a similar item but again not a single person has done so after emailing 2 apparently senior managers Sameer and Tshepo. this company has given me the run around and nobody cares about customer service. worst service I have ever received. wouldn't recommend this company to do business with.
