Shocking after sales service

Hi I have been trying to get the Company to come back to me regarding batteries which are 4 months old and not keeping their charge since end November 2022. This is now the 3rd time I have placed this on this media promises to get back to me never happen. Promises to phone contact me never happens. This Company feels nothing for their clients. Promises, promises but nothing. I have proof of all the e-mails sent but this company just ignores e-mail etc. I will never support this company again. Or the Company is now waiting for the Guarantee to expire. Next step from here is the Consumer Protection Board
