Faulty phone and disgusting service

I bought a Huawei Y5 on the 29th of June 2020 in Fourways. The phone screen kept going black, freezing and at times the keyboard would'nt pop up. I returned it to the Sandton store as that is nearby on the 5th of July 2020. They refused to assist me as they told me that I have to return it where I bought. I called head office and a lady by Thandiswa tried to speak to them. They then told me to return the phone to the fourways branch the following day. I did so (today). The manager Mhlengi wasnt at all helpful. They refused to refund me. They told me they will send the phone for assessment and repairs. The slip clearly states that an exchange would happen as long as it is in 7 days and anything either than that would be for repairs. I am utterly disgusted by the level of service i have received from Ackermans. I was forced to roam around johannesburg with a toddler who kept touching everything in the store. I can see that Covid 19 is also not a concern for you. please refund me my money and keep your ****py phone. That's my time, money and petrol. not to mention my health u are putting at risk.
