ADT non performance

on 28 december i had a break in at my residence . i have been dealing with adt for a few years now with an alarm system fitted by ADT. I requested the to come and give me a quote to fit additional security beams to my home . 30th dec i received a quote R2391.62 which i signed and paid for . I was told that they would be in touch with me to arrange for fitting of the beams . Tecnician arrived on 13 jan 2021 2 hrs later than agreed and i was subsequently told that the person who issued the quote had failed to inform the technical staff that trunking had to be done and thus they could not fit the beams . Subsequently i have not heard from ADT and i requested a refund for work which they could not do and i have purchased additional security cameras and fitted addition burglar bars to my windows . when i call them on *** all they say is they will escalate my querie but nothing happens . I am really fed up with this pathetic service
