Renault very disappointing

Trying to contact Renault for any help is a mission. I took my vehicle in for a repair in November 2019, had alot of delays, eventually received it in Jan 2020, saw a scratch which I know was not there and I have been trying to get it sorted out since then, understandably we went into lockdown but when we entered level 3 I expected some feedback, I had contacted the person I was liaising with via email as I tried calling many times with no answer. I just wanted this problem sorted out asap but renault is full of delays. Tried calling head office you only get put on hold with nobody that actually assists you. Very frustrating, no proper aftersales or communication unlike other companies,disappointing.
