Telkom non service

This is on behalf of my 74 year old mother that has been 1.) Experiencing problems with ADSL Telkom line for months and 2.) Now the phone landline hasn't been working for 2weeks I have phoned telkom on numerous times and it seems no one at that business can resolve the problem,but without fail the account is paid every month with bad service from telkom. The last reference was from Jabulile on the 17th February for a tecnician. This problem was 1st reported on the 4th November 2017 with the intermitted ADSL connection Ref 155CRK041117 and 27th December 2017 Ref 171CRK271217,I then received correspondence on the ; 30th Dec 2017 2nd Jan 2018 5th Jan 2018 8th Jan 2018 That my fault will be attended to but in all this time a technician arrived only one time to check on the problem and he could not fix it and would escalated to another department. The last communication with Telkom was a text on the 27th Jan 2018 with Ref 171CRK271217.
